Sorry, but it is the wrong one. Michael Hartman Dillow died in NC. He was in Pa as an immigrant but moved on to NC. Most of his line came to southern Illinos.
You must be thinking of Michael Dillow and Fort Dillow in Pa. They are two different fellows. The one at Fort Dillow in Pa. descends from the group that descends from Pierre Delon/Dulon that came over from France. I have been doing genealogy on both my Dillow lines since 1982.
My father is of the Virinia line and his mother through females goes to Michael Hartman Dillow. :)
