I don't know if you are related to my husbands family or not. But his second cousin was Henry Miller who's mothers name is believed to be Sophia (Wamboldt) Miller. Henry had possible three brothers but my husbands Grandmother can't remember for sure.I do know from searching for Wamboldt's most are in Colarado or Wisconsin. Those two seem to be the biggest consentration of Wamboldt's in the U.S. We Will talk to my husbands Cousin and find out for sure if his Grandfather's name was Conrad. Will check this site periodically.
