Hello, Kathleen, i live in Łancut and i have a book about Przedmieście (a suburb of Łańcut town).
The author wrote about many aspects of live in Przedmieście, he included also in his book chapter about emigration abroad. He mentioned many people that went abroad, he mention Wawrzkiewicz family. Let me quote what he writes just after Wawrzkiewicz family:
"And probably also two other families [has immigrated] kindreded to them [Wawrzkiewicz's] which was family of Paul Jabłoński (1872) son of Andrew and Anna Kochman, Pauls' wife Katharine (1884) dauther of Frank Kwolek and Josephine Wanowicz, one of dauther of Paul and Katharine which would be Caroline (1905) or Stanisława (1908). Second family was Catharine (1882) a dauther of Andrew Jabłoński and Anna Kochman, who emmigrated with her son John and her relative a Kazimiera Frączek (1886) and Anthony Sołtys son of Frank and Anna Dragoń. Kazimiera and Anthony married on 26.05.1907."
Dates in brackets are birth dates. Basing on this part, looks like there are many relatives of Andrew Jabłoński that went to USA. I hope i gave some new and helpful information.
