That is one of the puzzles I am trying to solve.I have the marriage application from Iowa Co., Wisconsin for Samuel George and Sarah Wilcox. dated 1847 and I have found that Samuel George brought or sold land to Howards, also in Wisconsin. There is a reference to him in the history of La Fayette, Wisconsin. Then I find Sarah Wilcox married in Illinois to Alexander Martin. Her father was John Wilcox if my information is correct. That is all I have about the name Wilcox so far.
