This register records births for Jews living in the villages surrounding Mociu (Hung: Mócs); there are a few entries for Jews living in Mociu itself. Probably the book was either kept in Mociu or stored there in later years and thus is catalogued as being from that village. The headings and entries are in Hungarian and the information was, in general, entered chronologically, with a few exceptions. The register was kept relatively well with all data completed in most instances. Name, date, gender, parents, marital status of parents, parent residence, midwife name, circumcision or naming ceremony details and name of witnesses or godparents are provided.
