Wondering WHY my ancestor left Lorraine in 1869, right before the War. He talked about the Franco Prussian War and we always supposed he took part in it. He was French, but settled in a German Catholic area of mostly Luxembourg immigrants. As far as I can tell, he was the only person in his family to immigrate to America. His father was Henri Hermann, or Harmann. My ancestor's name was Jean Pierre Harmann (that's how he spelled his name in America), born in 1839. Any pointers anyone can give me?
