I have an excellent article on George Chappell and his roots and descendants: Gale Ion Harris, "George Chappell of Windsor, Wethersfield, and New London, Connecticut" (New England Historical Genealogical Register, Vol. 150, 1996, pp.48-73. After Noah, I just have the names and dates of virth of his children.
It is interesting that both George Chappell and my ancestor, William Chapel, ended up in New London at the same time. Unfortunately for me, more is known about George.
