It is possible that your Thomas Kirkley may have been the brother of my John Kirkley and a son of Rachel Kirkley. A Thomas was mentioned in some estate papers as Rachel's son and yours fits the age that the census reports reflect for Rachel's family. I don't know anything about Rachel's Thomas and have never run across your Madison Kirkley. Can you provide any more info? What part of Chesterfield Co. were they from, where did they move to, names of Madison's siblings and children, etc. Anything would help. Thanks.
