Ed, Your Thomas Dickerson is brother to my Sybil Dickerson. Here's what I got from Old Fairfield, Jacobus, vol. 1, p. 182: The name was usually spelled Dickerson but occasionally Dickinson, of which it was a variant; Thomas Dickerson (Daniel's grandfather)had a grant of a homelot in Fairfield, 16 Feb 1656, which he sold to John Foster. The convenient death of Nicholas Pinion's wife Elizabeth in 1667, the same year that Mary lost her Finch husband, left him an eligible widower for this alliance; on 20 Feb 1677/8, Thomas Dickerson Jr. receipted to James [Joseph James, Thomas's sister Mary's husband] for the full rent for the whole number of years James had had the farm. Also, from New England Families before 16?? (also about Daniel's grandfather): THOMAS, Fairfield, had been at New Haven 1642, and it is unknown when he removed to Fairfield, but there he died about 1658, his inv. being of 11 September 1659, leaving Thomas, 2 daughters and widow Mary. The Richard Whitney information is intriguing. I checked all of Thomas's sisters; none married a Whitney. Sorry I couldn't enlighten on your main question, but I hope the other info is of use. Do you have any information on Thomas the elder (father of Thomas, Lydia's husband)? Like his birthdate, parents, wife's parents... Jeanne White
