Robert...I, too, am descended from William and Mary Felt Walcott through their son William, b. 23 Oct 1717. I have Moses and Lydia Mains Felt as the parents of Mary Felt. Moses Felt, b. @ 1651, was the son of George and Elizabeth (Wilkinson?) Felt. Lydia Mains, b. @ 1657 in North Yarmouth, ME, was the daughter of John and Elizabeth Laurie Mains (which could have been Mayne). George Felt's father was William Felt (Felch or Felce), bap. 28 Feb 1609/10 in Leighton-Buzzard, Bedfordshire, England.The name Mains could be from Devonshire, England. BTW, Mary Felt married William Walcott on 6 Aug 1712 in Salem, MA. I have more info on these families if you want to contact me.
