Hello Cousin, as my lineage comes from William's sister, Mary Catherine who m. my g-g-g-grandfather Reuben Rundle (Reynolds). I also would like to learn more about Delilah's father, as all I have was his place of birth,but no year, nor did Amy Gavett ever finds out anything during her research back in the early 1920's. If you learn anything more about William's father-in-law, then I also would appreciate learning what you found out that is if its OK with you. I never been to see George Washington grave site but have been to the Gavett Cemetery several times, when I made my visits to Delaware County. Wish you success in leaning more about the GREEN side of the family. Alan
