Mohel book
# Mohel book

The Jewish circumcision ceremony, brit mila, is enacted by a trained specialist called a mohel. Typically, mohels record the circumcisions they have performed in small mohel books, which have become especially important in the field of genealogical research.

## Use and format

The first pages of a mohel book are typically dedicated to the special prayers recited during brit mila.

The remaining pages are used to record the details of circumcisions, usually the place, date and name of the boy who was circumcised.

Mohels often chose smaller books for this purpose, so they could easily be carried around. Often, they decorated the books and title pages to look like medieval manuscripts. From the 18th century, blank mohel books were printed especially for circumcision entries. Today, the entries are usually digital, and efforts are being made to digitalise existing mohel books as well.

## Importance for genealogical and geographical research

While Christian births were documented in baptismal registries, Jewish births were not recorded systematically. In central Europe, birth registers were only introduced after 1876 (excepting France). Prior to this, Jewish cemeteries and mohel books were the most reliable records of Jewish family names and place. However, these books often remained in private hands, making them hard to access for scholars and families doing genealogical research.

Mohel books in combination with cemeteries and place names can give an overview of the movement of Jews in Europe in the Middle Ages and later centuries.
