I'd be happy to! They were from Balbierischkas (sp?) Lithuania which I've seen listed as being in the provinces of Kovno Lithuania and Suwalki Poland (due to border changes). They were originally of German ethnicity. Balbierischkas was a large Jewish area from everything I've found but my relatives were Lutheran. Because of the Rosenbaum records, I've wondered if they had Jewish friends that had also immigrated to Philadelphia who referred them to the bank (or i'm going to find out they were Jewish originally!). My g-grandmother's brother funded through the bank the passage for their mother, her and 2 of her siblings who then arrived in 1890. Their father and another brother had all come over together a couple of years earlier for work, I'm assuming. They moved to Brooklyn shortly thereafter for reasons unknown. Let me know if you have any other questions!
