After my examination of the second Chase/Chace family Facebook post from the Swansea Historical Society I can see that the information they had for Hezekiah's second marriage was probably inaccurate.
The second post, about another Chase/Chace family tree showed Pricilla Perry as the wife of William Chase, married in 1732! It didn't seem to me that there could be 2 women with the same name married in the same year...although the gene pools were small in those days.
I'd like to make a suggestion, though, that someone go back to Hezekiah's profile and remove the Little Compton Families source along with the image of the page attached to that profile as I now believe it to be misleading.
Also, there's a sentence in the biography which is spatially fragmented for some reason...
Thanks for your attention to my questions, John!
