Since I started my question in 1998, I haven't really looked at the message boards. I should have. In 2007 my wife and I spent a week in Wallingford, took pictures of the graves, spent time in the city hall and visited with relatives in Manchester and Farmington. I also sat down with Warren Williams and his wife, Penny. She directed me up a hill in a housing development that overlooked the area where the Williams' farms used to be. Took a long-distance picture or two of Uncle Shelton's place. I used to go there with my grandmother to visit her mother, Alida Williams, who died when I was six or seven years old (1959).
If you're still connected to Ancestry, I'd love to hear from you.
