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,
