I need help on my Mayo ancestor. My ancestor had brother Valentine Williamson Mayo, 1823-1884. She had sisters Rachel, Elizabeth and Sarah. There were in southern Indiana in 1835. Because of the given name clue, I feel sure they are related to the John Mayo (married Judith Corn and lived in Perry & Dubois Counties) but his only brother has an entirely different set of children. I have looked for this guy for many years but am no closer than 20 years ago. He must be either the son or the grandson of the James who married Martha Williamson, but I cannot fit him in this family anywhere.
