Thanks Elizabeth . That there were relatives of Manx Corkills around in Penzance while Canon Maddrell was there is 99% certain - they were my ancestors, the Corkells. What I dont know is which branch of the Manx Corkills these Penzance Corkells were related to. It was only a long shot but I was hoping that maybe something might turn up in connection with Canon Maddrell (who knew/knew of both Manx and Cornish families) which might help me find this out (eg if I knew where his IOM base was when/before he was staying in Penzance and then found that this was near one particular branch of the Corkill family, then this might tell me something). Thats the theory anyway!
