I think we have the correct parents for your william - Finlo + children etc can be traced via wills, lib vas and deeds (the set of names is also quite different) - haven't found the link to Maughold that Sue makes however - Peter Corkill of Ballafaile will 1741 - he was not in lib assed in 1721 nor in 1740 - possibly he was a tenant to possibly Wm Christian or Wm Callow, can't find any deed of sale (think other Peter Corkills of Maughold have 'name' links via Peter Looney)
