I wasn't suggesting that these Braddan Corkills who moved to Maughold were the ones Kurt is looking for - just mentioning the coincidence of the several Peter Corkills (& occasional Dorothy) in their lines.
It seems unlikely that they would be named after a Peter Looney when, for example, they had a father and/or grandfather also named Peter Corkill.
Re. Peter Corkill of Ballafaile/Ballafayle, please see:
www.isle-of-man.com/genealogy/messageboard/index.pl/md/read/id/552533
which shows the marriage settlement of Ballafayle/Ballafail to William Christian & wife-to-be Margaret Corkill (daur of Peter Corkill & Joney Quirk - and Peter & Joney's apparent residence there).
