Lithuanians in Brazil!? o.O Talking about people escaping from the cold...
No, it's my stepfather's surname. My biological father is originally from Brazil. His surname (& mine) is German.
But there are Lithuanians in Brazil, actually more than in the United States. There may be as many as 1 million Brazilians with some Lithuanian ancestry.
I have two surnames in Spanish, and whenever I tell people my second last name they always tell me how weird it is: "Chamagua", well probably of Native American origins.
I've never seen it before.
