A bit about how the encyclopedia came to be (and where it’s going)

I want to explain a bit about how the B&F Encyclopedia of Jewish Genealogy was put together, and what some of the issues I still have in getting to to where I want it. First, my name is Philip Trauring, since 2010 the author of the Blood and Frogs: Jewish Genealogy and More blog, of which this encyclopedia is a part. I’ve been researching my own genealogy for over twenty years, and have volunteered for various Jewish genealogy organizations during that time, including the Israel Genealogical Society (where I founded the Modi’in branch), the Israel Genealogy Research Association (where I am currently President), and Gesher Galicia. For more information on me, see my slightly longer personal introduction from my blog.

For years I’ve helped people with their genealogy who messaged me via the Contact page on this blog, and via the blog’s Facebook page (facebook.com/jewishgenealogy). Sometimes helping someone simply consisted of pointing them to the right resource online, one they were not aware of. One person can’t be an expert on every genealogy resource, however, and that would frequently mean searching online for the proper resource, or contacting someone else who I knew had experience researching family from a certain area. I’ve even found experienced genealogists who simply didn’t know a relevant resource was available (genteam.at comes to mind for those researching family from Austria – many people don’t seem to know about this amazing resource with over 14 million records in their database). With that in mind I wanted to create a way for all researchers to find the resources that are available, and if they know of others not in the database, to share what they know. Compiling the initial database of resources to launch with the encyclopedia was certainly a learning experience for me, and I discovered many interesting resources I wasn’t previously aware of, which I’ve been able to incorporate into the encyclopedia. With a little help from people using this encyclopedia, I think we can grow the number of resources many times over.

Like many things, if I had know how much time it would take to get this put together, I probably would never have started working on it. When I came up with the idea of putting together resources for Jewish genealogy in different countries, I thought it would be easy. I put together a list of countries based on the US State Department list, and created the first couple of pages on my site. I started collecting resources for Afghanistan and Albania. After working on just those two countries I realized there was no way I could put together the pages manually. First, it was too much work, and second, there would be no easy way to update the pages.

Wordpress allows you to create custom fields for pages, and I thus set out to put the data into those custom fields and then pull that data into a template for each country. The first step was collecting the data for each country (topics) and then collecting all the information online I could find for that country (resources). I ended up with 207 countries and 73 sub-regions (States in the US, Provinces in Canada, and I don’t know what you call the parts of the United Kingdom). Once I had a stable set of topics (280) I set out to add resources in my seven categories. At some point I gave up trying to add every possible resource for every country and region. Perfection they say is the enemy of good, and I wanted the encyclopedia to see the light of day. I ended up with over 1200 resources that I personally added. I imagine it can grow significantly with the help of everyone who uses this site.

Keep in mind that I left many resources out, and much of them on purpose. For one, I left the United States virtually empty of resources. Initially I only added resources for a single state to test, although after building most of the site I did go back and add a few resources per state to get things started. Other obvious countries are also short on resources. It will be up to the users of this site to help contribute resources to fill out what is missing.

There was a lot of thought that went into how to display all the resources available, and there have been many iterations in how I’ve displayed the resources. For example, initially websites and their social network accounts were considered separate records. The problem was that a single site with accounts on Facebook, Twitter, Youtube, etc. could take up many lines in the resource listing. Add to that multiple languages, and a single site could have as many as ten different links, and thus ten lines in the listing. That was not ideal, so I worked very hard to insure that for those kinds of resources, everything would be combined into a single listing. This approach is not without compromise. When a resource has multiple languages and multiple social media accounts, it can be difficult to know which language a social media account is in, as one example. In general social media accounts are the same language as the primary record, but not in all cases.

Another issue is what to do when a resource covers more than one topic. Sometimes an article will discuss two or three countries – should the resource be listed only once in one of those countries? Should it be listed more than once so it shows up in each country? There’s no easy way using my current tools to link to a single resource from multiple topics.

On a related note, some resources can easily fit within multiple sections within a topic. In those cases I’ve just picked the one I felt was most relevant. If the site has genealogical data, in general the category will be Genealogy. If the resource is related to a cemetery, it’s in Cemeteries, even if there is genealogical data. It’s definitely subjective, so it’s worth checking out all resources for a topic to see what exactly is available from each one.

I’ve only started to work on the addition of Cities to the encyclopedia, and have only done so with cities in Poland. This added 16 Provinces and roughly 1000 Cities. Adding resources for every city in the world would probably be a full time job for several people. Adding just the resources for the thousand or so Polish cities I’ve added so far (and I plan to add more cities) took months of work. Short of getting a significant grant to add cities in other countries, that aspect of the encyclopedia will stay Poland-only for the foreseeable future. As it stands now, there are over 10,000 resources already linked to those thousand cities, so I can’t even imagine how big the site would be if Cities were added to all countries. One other related point, when I say Cities I don’t differentiate between cities, towns and villages. Indeed most of those 1000 ‘Cities’ are probably just villages, or towns. Very few are indeed cities in the traditional sense.

Another type of topic I’ve toyed with adding is Historical Region. Some regions don’t map easily to an existing country, or had its Jewish peak when under the administration of different countries. Some examples that come to mind are Galicia (now partly in Poland and Ukraine), Courland, Danzig, and the Pale of Settlement. Each of these regions have considerable genealogical resources dedicated to them, and might therefore best have their own topics. Additionally, would Cities be added to the current Country, or the Historical Region? A complicated issue. For the moment, I’ve put Historical Regions on hold while I get current regions working.

I’m not sure what the best way is to keep the site updated. At launch I offer two methods for suggesting updates. Users can comment on a Topic to suggest a new resource or an update. There is also a link on the bottom of every Topic that directs users to a form where they can enter updates (this is preferred since it insures that all the relevant information is added). It would be nice to come up with a more collaborative method of doing updates, but I don’t currently have a good way to collaborate beyond what I’ve provided.

I have a field for each topic I call the Description, but which is currently being used to provide a translation of sources that are written in languages other than English. Ideally I’d like to expand the use of that field, or more likely a second field, to provide short descriptions of each resource, but I did not have time to do that before launch. I’ve also considered writing introductions for each topic, but that will need to wait until I have more time. For the time being I’m hoping users of the site will add their own comments on the resources to the resource pages.

When doing my research into resources for various countries, many times I ran into dead links, or links to sites that no longer exist. In some cases I’ve linked to a copy of those sites on the Internet Archive’s Wayback Machine, although those backups unfortunately don’t always contain the complete site. Sometimes when coming across a site that looked like it hadn’t been updated in a long time, or otherwise looked like it might disappear in the future, I’ve made my own local copy of the resource. In those cases there is a link to the local copy of the resource next to the main link.

I would also like to move beyond geographic topics, as not everything is so easily categorized geographically. Certainly an encyclopedia on Jewish genealogy should have topics about Jewish names, rabbinic genealogy, etc. Those will come, but not until I feel the geographic resources have been fully fleshed out.

So that’s a bit about how the encyclopedia came to be, and some of the technical issues I’m still dealing with in getting it to where I want it to be. Please let me know what you think about the encyclopedia in the comments, and feel free to post suggestions on the Improve the Site page.

Introducing the B&F Encyclopedia of Jewish Genealogy

For those who follow this blog, you might have wondered why there hasn’t been much activity lately. It’s not because I haven’t been working on the site, but rather that’s I’ve been working too hard on the site. I’m proud to introduce the newest feature, the B&F Encyclopedia of Jewish Genealogy.


I’ll be filling in the details in future posts, but in short the encyclopedia is a directory of online resources related to Jewish genealogy for each of more than 200 countries, and over 80 provinces (provinces are currently only in place for Canada, Poland, the UK, and the US). To seed these countries and provinces, I’ve personally added over 1200 resources to them.

For Poland, in addition to its 16 provinces, there are also roughly a thousand cities. This is experimental, but for those thousand cities are over 10,000 resources.

Each resource, which can be assigned to either a Country, Province, or City, can be in one of seven different categories: History, Genealogy, Cemeteries, Holocaust, Diaspora, Contemporary and Books. These resources are all intended to help one researching their Jewish families from these areas, and while they don’t all provide specific genealogical information, they are all intended to offer some piece of the puzzle one can use to pursue their research.

For Cities, there is an additional section, General, which lists general resources for the city, allowing you to double-check that you are looking at the correct city (and not another city that has the same or similar name).

For more details on all of the above sections, see About the Encyclopedia.

The goal of the encyclopedia is not simply to provide a list of links, but rather to be interactive and provide users with the ability to comment on specific topics and resources. When looking at list of resources for a given topic, each resource has two links. The first link takes you out of the encyclopedia to the resource itself. The second link takes you to a page about the resource, offering more details if available, and allowing users to comment on the resource.

This is just the beginning, but I hope people will find what’s available useful, and I hope you’ll join in the discussions throughout the site on different resources and topics. I’ll be filling in additional information about the encyclopedia and the resources on it in the coming weeks. In the meantime, enjoy exploring the site and I’d love to hear from users about what they like and what they don’t like. I have a page set up specifically where you can publicly post your ideas on how to improve the site, but you can also reach me through the regular Contact page.

Jewish Names from the Encyclopedia of Religion and Ethics (1917)

Encyclopedia-Religion-Ethics-Names-JewishIsrael Abrahams was the editor, from 1888 to 1908, of the Jewish Quarterly Review. He taught at Jews’ College, London, before he became a reader of Talmudics at the Univeristy of Cambridge from 1902 to his death in 1925. He was perhaps best known for his work, Jewish Life in the Middle Ages, published in 1896.

Between 1908 and 1926, the Encyclopedia of Religion and Ethics was published. In volume 9, published in 1917, is an article titled NAMES (Jewish) written by Abrahams. The entire encyclopedia can be downloaded from Archive.org, although I’ve made a PDF of just the page with the entry.

I’ve provided the full text of the article below, with minor changes. These include adding some paragraph breaks to make it easier to read, expanding most abbreviations, and adding links to many of the sources referenced.

NAMES (Jewish) — The post-Biblical period shows much the same general phenomena as are discernible in the Biblical age (see NAMES[Hebrew]; HDB iii. 478 ff.; and George Buchanan Gray, Hebrew Proper Names, London, 1896 — see copy on the Internet Archive – PT). The most significant modification concerns the marking of family sequence by the application to descendants of names borne by ancestors. In Palestine the naming of children after their grandfather can be traced only to the Greek period, about the 3rd century B.C. But the Elephantine papyri carry the custom back some two centuries for the Egyptian Jews (Gray, in Studien zur semitischen Philologie, Giessen, 1914, p. 161 ff.).

In the Rabbinic period the custom was well established, and it was recognized that a change had occurred from the older Israelite practice of naming a child after some circumstance at his birth. The change was justified by Rabbis of the 2nd century A.D. on two grounds: (1) the need of aiding the preservation of family genealogies, and (2) the loss of the guidance of the Holy Spirit in selecting the incident which was to be enshrined in the child’s name (Midrash Genesis Rabbäh, xxxvii. — see this passage in translation in the Internet Archive, pg 299. — PT).

It has never become customary for Jewish children to bear their parents’ names; there are exceptions, but in most cases the child seems to have been posthumous. More usual is the choice of the grandfather’s name, though the tendency has been, since the 13th century, not to name a child after a living relative (Leopold Löw, Die Lebensalter in der Jüdischen Literatur, Szegedin, 1875, p.95). (This has been the custom of Ashkenzai Jews since 13th century, but not of Sephardi Jews who do name after living relatives, particularly grandparents. – PT)

A full study of the history of Jewish personal names throughout the ages was published by Leopold Zunz in 1836 (reprinted in Zunz’s Gesammelte Schriften, Berlin, 1876, ii. 1-82). At that time the Prussian Government, following a Bohemian precedent of 1787, was proposing to introduce legislation restricting the Jews to Biblical personal names (cf. Joseph Jacobs, in Jewish Encyclopedia ix. 156 f.). Zunz had no difficulty in demonstrating that Jews had freely used non-Biblical names, adopting in succession Babylonian, Persian, Aramaic, Greek, Latin, Arabic, and later European designations. Many Hebrew names were translated into the vernaculars of Europe and Asia. Zunz’s work contains long lists of the Jewish names of various periods; and there are some similar lists in Jacobs’ article. In these lists Biblical names by no means predominate. The variety of Jewish names revealed in the English records of the 12th and 13th centuries is very remarkable.

With regard to surnames, there are indications that descriptive epithets were becoming common in the Rabbinic period, and that these were developed chiefly in lands where Arabic influence prevailed. Family-names were turned in surnames; so were place-names. The many wanderings of the Jews in the Middles Ages and more recent times induced the custom of naming a new settler after the town of country from which he had migrated. Then, again, such terms as Cohen and Levi, originally descriptive of descent, became surnames. Such names as Maimuni (or Maimonides), i.e. ‘son of Maimon,’ in the 12th century, and Mendelssohn, ‘son of Mendel,’ in the 18th, are illustrations of the practice of converting the father’s personal name into a surname.

Animal namers are probably more common among Jews than among the general population (See my article Animals and Name Pairs in Jewish Given Names on this topic – PT). In the mediæval period occupations suggested many names, and in the centuries approaching the modern age names were derived, especially in Germany, from the business signs (such as the red shield which gave the Rothschilds their name). The intercourse between Jews and their fellow-citizens after the emancipation period rendered it necessary for the former to bear distinctive civic names. This had been the case long before in Spain, and was growing common throughout Europe when, in 1787, the custom became regular in Central and Northern Europe. In the year named the Jews of the Austrian empire were ordered by law to adopt surnames; if any refused, the registration commissioners were empowered to enforce names of their own selection (cf. Jacobs, loc. cit.).

The naming of the child has at various times been a ceremony of considerable moment. The period covered by Scripture is fully dealt with in the Bible Dictionaries and in article NAMES (Hebrew). From the 12th century, according to Löw (p. 97), not earlier, Jewish boys were names on their eighth day, during the circumcision rite. The formulæ vary; the now common form may be found in the Authorized Daily Prayer Book (ed. Simeon Singer, London, 1914, p. 305 (See a copy of the American edition of Singer’s siddur at the Internet Archive – in this edition look for page 449 – PT); cf. Löw, p. 101). A formula for the naming of girls is given in some rites (see Book of Prayer . . . according to the Custom of the Spanish and Portuguese Jews, ed. Moses Gaster, London, 1901, i. 180); it is becoming customary to name girls at the first visit paid by the mother to the Synagogue after the birth of the child (Singer, p. 312).

The names thus given are mostly in Hebrew, though sometimes the vernacular names are merely transliterated into Hebrew letters – a custom which goes back to Talmudic times. Such names as Alexander and Julian were this treated in the Rabbinic age. Often the Hebrew and common names corresponded either exactly or in meaning, but in modern times there is frequently no exact correspondence between the Hebrew and ordinary names; this the chief Rabbi Hermann Adler had the name Naphtali. There is, however, some remote connexion in meaning between the two names. It is still customary to find a Hebrew name beginning with the same letter as the vernacular name. Most Jews still bear two names (though the two are often identical), the one Hebrew (termed ‘sacred name’ and used in Hebrew documents, in the Synagogue, in epitaphs, and so forth), the other vernacular (termed ‘common name,’ used for ordinary purposes).

The Hebrew names thus conferred are borne throughout life, except that, under Kabbalistic influence, some rites direct the change of name in case of illness, in a prayer for the patient’s recovery (for a formula see Gaster, p. 195). This custom is now more honoured in the breach than in the observance, though it has some Talmudic authority, for in Talmud Bavli (Babylonian) Rosh Hashanah, 16b, mention is made of the efficiacy of a change of name.

Names are still changed on conversion thus a Jewish convert to Christianity is given a new name, such as Paul, while a convert to Judaism receives a patriarchal name (Abraham, Sarah, or the like). On the other hand, it was held by the Rabbis a meritorious trait in the sons of Jacob that in their Egyptian environment ‘they did not change their names’ (Leviticus Rabbah, xxxii. 5).

A pleasant custom with regard to Hebrew names is the selection of a Scriptural text, beginning and ending with the same letters as the Hebrew name; the text is then a kind of motto for the bearer of the name. A long list of such texts may be found in Seligman Baer, Abodat Yisrael, Rödelheim, 1868, p. 106. (See the opensiddur.org project to transcribe Baer’s Avodat Yisroel – PT) Some have sought the source of this custom in the Talmudic references to an older school usage. ‘Repeat to me thy verse,’ says a visitor to the school (cf. the incidents recorded in Hagigah, 15a). But the verse in these passages was some recently-learned text, and apparently had no connexion with the pupil’s name.
