Checked the Maughold Film at the FHC today LDS # 0106735 Maughold Parish register 1650-1849

Wm s/o Patrick Corkill and Catherine Creech 28 Feb 1816 no other info and no place name

Wm s/o Thomas Corkhill(spelt with an H) and Eleanor Callow 12 May 1816 no other info and no place name.

So no real help from film to identify your William.
