Have you experimented with Ancestry ThruLines yet? If not, you have to check it out!
As I posted earlier, ThruLines suggested that Matilda Caroline Stoner was a granddaughter of James and Sally (Smith Duggins) Crawford.
Based on the family tree suggested by ThruLines, I was able to research the family of Matilda Caroline Stoner and William Harrison Fields. Thru that research I was able to follow descendants to my suggested DNA matches.
