I can't find proof that this Abigail Ross is the one who married John Hazeltine. This Abigail Ross
in the records I find married a Philemon Wood on 22 November 1704 in Ipswich. The Abigail
Ross who married John Hazeltine has different parents as far as I can find. WikiTree has her
listed: "ABIGAIL ROSS (daughter of FENNEL ROSS and HANNAH BULL) was born 28 Jan 1673
in Ipswich, Essex County, Massachusetts." and:
"There are a few women named Abigail Ross who may be conflated in this profile. These three are born in Ipswich, Massachusetts in similar time: https://ma-vitalrecords.org/MA/Essex/Ipswich/aBirthsR.shtml
[Ross] Abigaill, d. John, Oct. 14, 1672. CTR
[Ross] Abigaill, d. Fenell, Jan. 28, 1673. CTR
[Ross] Abigaill, d. Killicres, June 20, 1677. CTR
Online family trees seem to mix them up quite a lot."
Note: Fennel could be the brother of Gilchrist and arrived on the same ship Unity.
