My wife's fathers family came from Dembitz. Their last names are Cohen.
Among those who came to New York were Gussie (nickname??) Cohen, Louis Cohen, Anna Cohen and Joseph Cohen. They later had more brothers and sisters born here. Their parents were Solomon Cohen and wife Sara Blauner. I have a family tree of the Cohen family but go back only to Solomon Cohen and Sara Blauner with limited information about them.
The family changed their name from Cohen to Kohn when they came here.
