Thank you for responding. I have very little information on my Katzman line except . . .
Borach Katzman Abt. 1850-1913? married Selma Heller Abt. 1850-1912? both born Mogilev. Borach had a brother who was a land surveyer.
Borach and Selma (not really sure even if these are the right names!) had several children including:
Chasheh Katzman (probably not even the right spelling) who lived in Mogilev and is believed not to have immigrated with other siblings to the U.S. We know he married and had at least 2 children but do not know their names.
Mary Katzman immigrated to U.S. and married Isaac Steinbach but what her name was prior to immigration I don't know.
Harry Katzman immigrated to U.S. and married Bessie Stone. He may have had a different name prior to immigration and was born about 1890 in Mogilev of course.
Mayer Katzman did not immigrate from Mogilev and married and had 2 children names unknown to us.
Sarah Mollie Katzman who immigrated and married Louis Altshuler (my line). She was born 10/1880 about in Mogilev.
An unknown Katzman child who may have died in childhood from measles in Mogilev.
I know nothing of Borach's parents or siblings, but I thought maybe siblings might name children after aunts and uncles and grandparents who had died so maybe you might see common names with Katzman in your line?
Let me know if there is any possible connection here. Thank you.
