I have been researching my family history and I found many records on my great great grandfather Thomas Burba. I am confused as to what nationality he was though. On his Ship passenger list his last residence was listed as Sere. The 1910 census says he is fron Russ Lithuania. The 1920 census says he is from Siwalk Po Russia. His 1930 census says he is from Lithuania. Does anyone know what nationality he is?
If he is Lithuanian and was naturalized after my great granfather was born, can I get citizenship through him even though he is my great great grandfather?
