Depending on how old Bridget Cooley was in 1707 having another child in 1735 could be very reasonable.My own mother had my youngest brother when she was 42. The only info I have on Sarah is b. 1735, married in 1748 John York b.8 Dec 1728 in Standish, ME. And in1772 married her second husband Israel Thorn b. in Standish, MA which I believe is Standish, ME. MA and ME appears to be thrown back and forth since Maine was not a state until 1820.
