Kosta?
My great-grandfather carried this surname. He was, I believe, from Germany. I was talking to him one day, years ago, asking about where he came from and the origin of his last name, Cost. He said when he was a child, his family moved from Germany to America. To become more 'American', his family dropped the -a and changed the K to a C, according to him. I was wondering about this recently and would like some more information on the story, or at least confirmation. I would talk more to him about it, because I was 9 at the time, but he passed away shortly after and I don't have any other relatives who know anything about it. Any info at all would be helpful. Thanks in advance,

KOSTA is the new Greek coloq form of the name CONSTANTINE.Thus, Kosta as a family name (after some kind of shortening) might be of Greek or South Slavic origin as well.

Could be related in some way to the Czech surname Kostal, which is said to mean "spike", for a person of "spiky appearance". I take no responsibility for any of this, just quoting others. Czech names often have related names among the Sorbians (Slavs) of Germany.
Otherwise it might derive from the forename Konstantin, or, stretching things even further, from Gustav.

Thank you. It may have derived from the Italian surname 'de Costa' meaning 'the coast'. I'm not sure though.
