Thanks for your input, Craig. Here is what I found in Rhode Island Genealogical Register, Vol. 12, page 142. (abstracts of wills).
"Willcox,Thomas, of We, Wigmaker. Will dated 15 May 1754, proved 29 Nov 1757, pgs 525-526 and receipt pg 517. Mentions: wife Sarah Willcox. Elizabeth Goodwill eldest dau of my present wife's sister Elizabeth Goodwill. Witn: Stephen Babcock, Joseph Davis, Silas Greenman. Pg 531. Widow Sarah Willcox (this will) called Sarah Willcox alias Palmiter: she was paid for keeping Peter Palmiter. There is no mention here of any children of Thomas and/or Sarah.
My interpretation was that if Sarah was "alias Palmiter" that she was a Palmiter when she married Wilcox.
I have not been able to find a copy of the actual will. The Westerly town clerk's office states that they "cannot find it." The same story for everything that I have requested from this office.
From another researcher I received data that Jonathan Palmiter Jr. bc 1720 m 1st Phebe Cross and m 2nd in 1758, (or 1760?) Sarah Wilcox, who supposedly bore him 3 more children. I doubt that this is correct. At least I do not think that Sara Tefft, b 1715, would have had children by her 2nd marriage...1760-1765?
There were several Palmiters named Jonathan born in the same time frame and living in the Westerly/Hopkinton/Stonington area about the same time, and it is hard to figure out who each one was.
The Peter Palmiter that is mentioned had at least two nephews named Jonathan. The names of Peter's wife or children have not been found as yet. It would be a great help if I knew when Sarah "kept Peter Palmiter". Perhaps she married a son of Peter? Thanks again for your help.Jean
