Jean, I meant to say in my last message that you have probably checked for him in the 1881 census at FamilySearch.org? It has him at the Mans Arms, Census Place Onchan (LDS Film 1342346, PRO ref. RG11, Piece / Folio 5602 / 49, p.17) as Hugh MC CARTHY Head M Male aged 69 born Ireland, Hotel Keeper
Mary MC CARTHY Wife M Female 66 b. Ireland
Alice HOY Aunt W Female 82 Ireland Annuitant
Henry MC CLUSKEY Nephew U Male 24 Douglas, Isle of Man, Gardener
Elizabeth BARTON Serv U Female 15 Douglas, Isle of Man, Genl Serv Domestic.

Very useful to have both his aunt and nephew named when Irish research can be so difficult!

As a hotel keeper he probably appears in Frances Coakley's website Manx Notebook - see link at top of screen.
