suspect we may be at cross purposes - I suggested the John Clague + wife Elizth as strongly possible as noted having a dau Elizth of the right age + in right place - from the grave info then looks as tho Elizth w/o John was Elizth Harrison born Andreas (which parish supplied many of early Ohio settlers) but John Clague looks more of a mystery - s/o Robt + Elinor Corkan bapt Braddan would fit birth year but no on Island marriage I can see
