Dear Allen and Flo, According to another Thurman reseacher, Pricilla is not the Daughter of William and Susanna, but David Thurman. The first wife of Issac (not known)was the daughter of Wm. and Susannah. Allen, there was a Issac Ashlock in the civil war from Missouri. I think your Susannah's brother. He was in Co.F-18Mo- Infantry listed as a private.
