About Abiel Everell / Averell
The children of William and Abigail Averell whose names are known to us and appear in Ipswich town or court records, are the four given in the list below. The three whose names are unknown, of the "seven" mentioned in their father's will, may have been daughters, or some may have been younger sons. In any case, as Everill, Everell and Everall were variants of the name Averell or Averill as found in documents relating to this family, it seems wise to give elsewhere all that we know of James Everill or Everell of Boston, and Abiell Everill or Everell of Boston (they were not Everetts) ; and also, because of association with Ipswich, some items about Thomas Avery of Salem, for which see under A. B. C. in "Memoranda" below.
