I have a copy of the entry the priest made in the marriage book at the church, he was skimpy on this entry :-(
Basically it says, Karolus Trimbath and Maria Buksar 1917 May 15, along with name of Testes Martrimonii: John Galac and Anna Belks, Minister is Rev Geo. Malinik. He left everything else blank!.
His WWII registration has him born in Cambria PA.
My grandmother didn't like the fact he was foreign born and she may have convinced him to use a PA birth location to sooth her, she was very very strong willed. This might be why there was no Alien Registration form filed.
As for being adopted, he was left here alone in the US (he always said he was only 10 years old. The story is his father was killed in a bar fight and his mother wanted to go back to old country. He went to work in the mines and was taken under the wing of the Trimbath family. A member of that Trimbath family remembers hearing his father (who is deceased) talk about Charley Trimbath and how their family took him in.
I have his SS-5, and it listed Haston, Cambria, PA
As for his birthdate, family says he never knew his birthday so he took the last day of the year, and made himself about the same age as my grandmother.
This guy is all over the map, I'd think he was on the run, if he wasn't so young when he married, hard to had another family to hide from at 21 or probably younger.
