Hello Averil,

I can't see them there in 1841, but they are in Maughold in 1851. (http://www.lawsons.ca/census/c51-l.html. 2524, 283, 103) You would have access to the two online Maughold censuses as a member of the FHS? 1841 & 1861 by Tom Corteen.

1861 has:
3 21 Marghakew Joseph LOONEY Head MAR 70 Farming 150 acres. Employing 2 labs Isle of Man
3 21 Marghakew Isabella LOONEY Wife MAR 50 Isle of Man
3 21 Marghakew John LOONEY Son 19 Assistant Isle of Man
3 21 Marghakew Mary LOONEY Daughter 16 Isle of Man
3 21 Marghakew Evan LOONEY Son 16 Maughold
3 21 Marghakew Robert LOONEY Son 10 Maughold
3 21 Marghakew Jane LOONEY Daughter 7 Maughold
3 21 Marghakew Ann CORKILL Servant 27 Servant Maughold
3 21 Marghakew David KINRADE Servant 10 Servant Maughold
3 21 Marghakew William CHRISTIAN Servant 18 Servant Maughold

The other Looney family you were looking at was there in 1841:
3 1 3 Highbernian Cottage Rachail LOONEY 54 Inn keeper Isle of Man
3 1 3 Highbernian Cottage John J LOONEY 21 Isle of Man
3 1 3 Highbernian Cottage Margaret LOONEY 23 Isle of Man
3 1 3 Highbernian Cottage Sarah LOONEY 20 Isle of Man
