My late father in law was born in Arad around 1905-1906. His last name was Don. This is not a Hungarian name, although he was. I believe it is the name of a river in Russia. I am trying to do genealogy on my husband's side of the family.
I believe my father in law had a brother, John and a sister, Clara. Neither of them were living when he came to the states after world war I.
I have no information on his parents.
How would I find a baptism/birth record for him that might name one or both of his parents?
