My ggm had a brother Lajos, whom my father was named for.
LDS shows a birth registry for Ludwig. I don't believe
that Lajos is a nickname, so all I can assume is that he
changed his name, perhaps preferring something Hungarian
to something Germanic. Any thoughts on this phenomenon.
He was born in Kunszentmiklos in the 1870's.
