Has anyone here linked Isaac Allerton descendents to either the Plympton (Plimpton), Willett or Guild families of Dedham, MA or the Wilkinson or Lewis families of Walpole, MA? My great-great grandmother Sarah Wilkinson Lewis Vaille (1824-1913) claimed Isaac Allerton as ancestor, but I have a couple of missing generations in there that I am trying to piece together. Other family names that may provide the link: Hale, Underwood, Richardson. There is a book on my family tracing back to the Plymptons and Lewises called "Lewis Farm: A New England Saga," published in 1950, author Priscilla Robertson that traces the family up to my mom's generation... but I still need to make the direct connection. Would greatly appreciate any help.
