not sure I understand - the M/c Wm cain + Mally is dated 1674 - I didn't see a marriage in Michael - Dollin is I think the first child bapt 1687 that names mother (and only 1st name Mary) but as Wm is at age in 1690 will he would fit the 1676 bapt (and would of course make a 1684 marriage impossible)
what is the problem with the 1716 family ? this is Wm Cain + Bahee Corkan m Mic 1703
