In a history written of Travis Franklin Hensley. It reads "Thomas Mullen was born in Loudoun County, VA, and was stationed at Fort Pitt at the close of the revolution and was mustered out at Philadelphia. He went from Loudoun County to Bourbon County, KY, in 1783. His family consisted of James, Richard, Nancy, Betsey, Asa, Sallie and William. (William is my 4th great grandfather.)
I do have documentation that shows Thomas died in 1832 in Kentucky. There is also research done by another family member many years ago that indicated Thomas was the son of Darby Mullen of Lisburn, Antrim, Northern Ireland, though I haven't been able to find absolute verification on this.
