A half second cousin once removed is descended from James Cady Chaffee and his 2nd, umm, live-in person. He is the one who told me about the 2nd "marriage." Apparently James C.left Lucy for Melinda Sales Denny, with whom he had 2 or 3 more children. We thought it was 2, but the 1880 Census has it as 3. Incidentally that same Census has for wife's name: marrn. I don't know for a fact but I am guessing that it means "married not." He can be found in Rock Falls, Whiteside Co, IL in the census. He died in 1882. He was a physician.
