Cousin Jeffery: Contact Me. I don't recall just when we lost contact with each other, so I don't know how much more information I, or you, have gathered. I have come across another Detert family in Wisconsin, a Douglas Detert. We've been emailing each other back and forth for some time now. His sister-in-law is living in Paris, France, and she is the geneological expert on the Deterts (their branch). I gave her info.
