Success! Well, almost. I made a little bit of head way with my father's family. For years, I was told the story that my G-Great Grandfather, Leo (aka. Leon) arrive in the U.S. at the age of 2 with his parents Wadislaw and Catherine. Apparently, this was incorrect. I found records that show Wadislaw arrived in Nanticoke two years prior to his wife and family. Leo was actually aged 6 and he had a sister, Stanislawa, who was two. There is nothing on Stanislawa after arriving in the U.S. so I would have to presume that she died shortly after. Recommendation: Look to the polish female version of spelling of the last name (example: Oborska).
