{geni:about_me} Moses Abraham Kohn-Zerkowitz lived in Turzovka, Trencin megye, Hungary, a town to the north of his birthplace of Bittse. He remained a member of the Bittse synagogue and is listed in the Bittse Jewish census of 1848:

Bittse (Synagogue), Trencin megye, Hungary, 1848:
Kohn, Mojzses, age 37, b. Bittse
wife, (Polak), Mari, age 34
son, Hirs, age 9
daughter, Anna, age 7
daughter, Neti, age 6
daughter, Pepi, age 4
daughter, Cili, age 3

Early in his life, he went only by "Kohn" (as his father had done). However, in the 1840s through 1850s, records consistently refer to him as "Moses Abraham Kohn-Zerkowitz". By the time he died in 1878, he had shifted exclusively to "Zerkowitz".
