First, thank you very much for your help!
The Jurgis you found is definitely my Great Grandfather; I didn’t know that his father was Juozas (Joseph). I am 75% sure that this is the Jurgis I am looking for; I spoke to my grandmother last night and found out that he had a brother Anthony who stayed in Lithuania, and a sister Mary who also stayed in Lithuania. My grandmother remembered Jurgis saying “if she thought was bad here in the USA, you should live with my poor sister Mary”. He supposedly had another brother whom my grandmother is trying to remember.
As for Valentine Gustainis, she says he is related to her also… I’m not sure where the Vinksnupiai village, Vilkaviskis district is. There is a reference book that also shows Valentine Gustainias
“GUSTAINIS, Valentinas, son of Vincas, born 1896, resided Zemojoje Panemuneje, Sakiu district and region,a journalist, exiled 1941, arrested in exile, 1946, released 1956 and return to Lithuania, died 1971.”
This is where I get stuck… I do think Ms. Fuller contacted me a few years back, but it was before I had some more detailed information…
