I'm at a loss where to look next. William Jenks names three daughters in his will but doesn't mention their married names. He references his deceased daughter Elizabeth's children, so its definitely a case of simply omitting the names (and not a sign that they were unmarried). William is originally from Rhode Island, and moved to Connecticut, but spent the last couple of decades in Tyringham, Berkshire, MA & Chatham, Columbia Co, NY.
There was info on Meribah in a book, but Waitstill's and Elizabeth's married names/husbands are unknown.
I suspect that Waitstill is the wife of Levi Wheelock. Levi sold land cheaply to William Jenks (either father or brother in Berkshire Co, MA. And also relocated to Columbia Co, NY around the same time as William Jenks.
Any additional clues, or thoughts of where to look would be greatly appreciated.
