I am looking for additional information, such as birth date, on Antoni Skowronska. He married Theophila Rydzynska on 10-17-1891 in Philadelphia and they had 2 children: Mieczyslaw (1892 in PA) and Stefania (1896-1971 born in Jersey City). By 1900, Stefania (aka Sophie) was living with her maternal grandparents and I don't know what happened to either parent after that. Family lore was that Antoni was "lost at sea" and Stefania's wedding documents say he was deceased by 1914. Theophila was also missing by 1914, but I have no death record. Any help?
