Yes, that's right - Tom Corteen. He lived there until a couple of years before he died. His ancestor Thomas Corteen 1706-1790 was supervisor to the daughter (my ancestor) of his youngest brother Edmond 1725-1761, and remembered her in his will. - 12 children, with Thomas the eldest son, and Edmond the youngest.
There is a very old Gedcom of Tom's on the Manx Genealogy website: http://www.isleofman.com/interests/genealogy/gedcom/index.asp
- but he had added a lot of details since then, and given Brian a number of will transcripts.
Those Maughold census transcripts on the FHS members-only online site are also his work.
