Quick summary: Esther might or might not have been born Mat(t)hews, a different Esther who apparently WAS Matthews married Daniel Willard in Yarmouth in 1695.
The main legitimate source for Esther the wife of William Hall is Anderson's "Great Migration" which unfortunately is self-contradictory regarding her marriage so this profile should be very much considered work-in-progress.
In Great Migration Vol 5 pg. 93 in the entry for James Matthews, his daughter Esther is given a specific birth date and location (8 Jan 1650/51 in Yarmouth, Massachusetts) as the daughter of James Matthews. This entry says she was "probably the woman of that name who married Daniel Willard in Yarmouth 10 Aug 1695" listing Plymouth Colony Records and Yarmouth Vital Records as primary sources. and  and for an actual primary source showing maiden name of Matthews, Yarmouth vital records.
In the same series Vol 2 pg 842-843 we find Esther Unknown as the wife of William Hall (son of immigrant John), married to him by 1683 or possibly as early as 1675. Here Anderson lists a source of "The Ebenezer Hanks Story" by Kerry William Bates which does not seem to be available online. Anderson says this source lists a "possible" son Isaac who married in 1700 (pushing Esther's likely marriage date back to maybe 1675) and notes that the source "suggests" that Esther may have been a daughter of James Matthews apparently based on the fact that James' daughter Mehitabel married Benjamin Hall, brother of William Hall.
Esther the wife of William Hall then appears in Mansfield (Connecticut) vital records as "Easter Hall, wife of Captain William Hall, d. 19 Feb 1726/27" while Esther the wife of Daniel Willard died 28 Jun 1726 in Yarmouth, Massachusetts and in the same place her husband Daniel died in 1712.
So in summary, none of this resolves whether Esther the wife of William Hall was born Matthews and if so, whether she was the daughter of James Matthews and sister of Mehitabel, wife of Benjamin Hall. However, it DOES mean that Esther the wife of William COULD NOT have been the wife of Daniel Willard, as this Esther was buried as the wife of William Hall in 1727 so we are dealing with 2 different Esthers.
More research on Daniel Willard and his wife Esther (apparently) Matthews probably needs to be done to resolve these uncertainties. The "Willard Genealogy" referenced by Great Migration may hold more clues. It states authoritatively, but without detailed sourcing, that Esther was the daughter of James Matthews.
