Hello, I have not worked on this part of the line for awhile, but just checked my notes. I think you may be right about the Sarah Hart part. This was from my early research and seemed to be a sort of general consensus on this line. However, in the meantime, I have gotten better at researching. The only things I am pretty sure about from records I have seen is that Elizabeth was Potter, not Porter, that she had a sister named Mary Potter who married Philip Richards, that Elizabeth married three times and was an active Quaker and not at all shy about speaking up, and that her father was probably a Quaker minister. She was in Oyster Bay, NY around the time she married Frampton, but there is also a reference to RI about the same time. She came to Philadelphia about 1683/4 according to Quaker records, and her sister is shown as coming from NY, as is Richards. So the clue will probably be finding a Quaker (minister) Potter in (probably) the Oyster Bay meeting who had children Mary & Elizabeth around 1650. I did find an Elizabeth Potter in that area who married around 1650 & who could have been a sister to "our" Elizabeth's father.
