I am looking for info on the above name and family, living on South St, in Philadelphia on the 1910 census. His wife is listed as Edith, head of household is Rebecca Belefsky (daughter-in-law?), children Abraham 19, born in PA, Rosie 14, Ida 10, Sarah 7. They are listed as Russian/Lithuanian, arriving in USA 1891. I have reason to believe their original name might have been a version of Belawski (Bieliauskas), similar to Belasco, which is the name I am trying to trace.
