We may have crossed research paths in the past, as I have been researching Lewis Duvall, oldest son of Dennis Duvall.
I too have read the section about Mary Duvall in the rather large book of “History of Fayette Co. PA”. In the section under Springhill Township it does say that Mary was the friend of Indians. It also states:”She left a family, mostly boys, who were said to have exhibited strong Indian peculiarities, both physical and mental.” I did NOT interpret this statement to mean that all of her children were fathered by Indians.
It is generally accepted that the three brothers that you mention in your post, are the sons of (John) Lewis Duvall and Margaret Driscal (Driskill). It is my understanding that Margaret Duvall outlived her husband and the Fayette County Tax Lists support this. Margaret Duvall is listed in the 1789 Fayette County Tax List, and the 1790 and 1800 US Federal Censuses. Both “Denis” Duvall and Daniel Duvall are listed as separate households in Springhill Township in the 1800 US Federal Census. The other son, John Lewis Duvall, had already migrated to Nelson County, KY and is listed in that county’s Tax List for 1800.
As the book states, Daniel did marry in Springhill Township, to Alycn Harden. But contrary to the book, the censuses show that his family stayed in Fayette County for some years before migrating to Darke County, Ohio. Dennis Duvall followed his brother, John Lewis Duvall, to Nelson and Bullitt Counties, KY. It is my understanding that this John Lewis Duvall was born about 1767. It would seem that he would not be old enough to be a soldier in the Revolutionary War. But, his father (John) Lewis Duvall may have been in the war. There was some discussion either in the Genealogy Posts or the Rootsweb Posts a couple of years ago, that the father was from the Maryland Duvall Line. I have not researched this path. But there is documentation that some of the Maryland Duvalls lived in St. Mary’s County, Maryland, which was considered the “Catholic” county, even though they were not Catholic.
When I read this passage from the book 6 months ago, I “assumed” Mary Duvall was Margaret Driscal Duvall, the wife of (John) Lewis Duvall. But there is nothing in the book that proves this. There is however, other additional documentation that strongly implies that Margaret Driscal Duvall is the mother of these three men: Dennis, John Lewis and Daniel.
So, either the Mary Duvall from the book is NOT the mother of these three brothers, or Mary Duvall from the book is Margaret Driscal Duvall.
Can anyone else add information to this discussion?
