(all of this is likely, but not 100%)
Fishell Yoselewitz, had many children, and
they lived near Borzna and Nezhin, Ukraine.
He had Benjamin Yoselevitz who married Bessie
Chalezky, and they had Nathan. They emigrated
to America about 1890. They moved to Philly
and also had Morris(Shea), Frank, and Irving.
All the sons married, but I think only Nathan'and Frank had
children. There might also have been a daughter
Dora who died young. Benjamin was gone by 1910.
Nathan changed his name to Nathan Nathans,
and soon everyone else was too. Nathan married Kate and had
Bernard, David, and Ruth Roseman.
Frank married first Sadie and had a daughter
Dorothy, and a son, whose name I don't know yet.
Sadie died at a young age and was sent to
live with Sadie's parents in New York City.
Frank later married Agnes and had Constance.
