Seeking JOHN BUSH of Somers, CT area d bef 1782

John Bush would have lived in the northwest corner of CT or the portion of MA that encompassed the towns of Wilbraham and Springfield.
John Bush died [no date found] and left his property to his [unnamed] wife, per his Will (so far not located)At least a portion of this property came into the hands of a Thomas Davis of Somers, CT.
The towns and their borders were fluid and changing during this time period.The area in question had been part of Enfield, CT, which was extended east and set off as Somers, CT, where Thomas Davis was living on his farm.
By 5/10/1782, Thomas sold a 40 acre farm portion of the property to his son Kitteridge.The deed described the land which then placed it in Wilbraham, MA.
About 1798 - 1800 Kitteridge and his family had removed to Winchester, VT and I presume that he sold his land in Wilbraham, MA.
I am trying
(A) to locate John Bush, his date & location of death,his Will and the name of his widow?.
(B) to determine how the property in question came into the hands of Thomas Davis?
(C) something that might help to identify the Correct Thomas, as there were several in the area at this time?.
(D) Any land transfers regarding John Bush, his Widow Bush and Thomas Davis?.
(E) Did widow Bush remarry?To Whom?Date & place of her birth & death?

Perhaps you can direct me futher to the Bush families in the CT / MA area.
