I am looking for information on Valetine Gustainas born 15 Jun 1896 in Vinkšnupiuose, Sintautai Parish. He married Isabel Avietiene born 24 Mar 1898 in Worcester, Massachusettes. Her parents, Adam J. (White) Avietenas and Magdalena Paulionis immigrated to the US about 1895.
I do know that this Valentine and Isabel had one daughter, Valentine (I have a photo of her) and one son. Per family history, Isabel sang opera and Valentine was some sort of political or diplomatic person. I have that Isabel and Valentine both died in Lithuania but only have a date for Valentine of 1971.
Isabel's mother is my greatgrandmother's sister.
Any information is appreciated.
