Leyb Shmul Kaplan married Esther Wallach and had a son Simon in 1899 born in Bielsk. His birth certificate said the family had been from Svisloch. I am not sure which side that would have been most likely the Kaplan side, as I am sure Esther was from Romania, but that could be wrong.
Family moved to Connecticut.
Pauline married Nathaniel Rosen in NYC
Samuel was a bachelor lived with Watnik Cousins in NYC.
Their Father was Samuel Kaplan, married to Asny Watnik.
I believe Samuel's father was Movshe, Moshe, Moses?
Anyone with these names?
