there was an illeg child Wm born to Cath Corlet in 1782 bapt 2 May 1782 - hand loom weaving at this period was a dying craft and poorly rewarded - I can't find Wm as having owned any property nor as far as I can see mentioned in any will.
Margt Clark was married in Kk Patrick wch suggests her family was there but Kk Patrick is easy walk from Peel - can't see any Clarks having children in Kk Patk to cover years matching her age in 1841 - the only matching Margt clarks are in Lezayre + Jurby.
