Going by the dates, John Ned's parents John Caley and Isabella Corkill probably married 20 May 1802 in Andreas. It would be useful to look at that marriage to see which one was from Maughold.

Children bapt Maughold (could be two families - there is rather a large gap after no.2):
Ewan [son of] John Caley/ Isabel Corkill [bapt] Parish Church 3 Jan 1803. Private baptism
John Ned John Caley/ Isabel Corkill Parish Church 24 Feb 1805
Elinor John Caley/ Isable Corkill Parish Church 15 Jul 1811. Private baptism
Esther John Caley/ Isabel Corkhill Parish Church 9 Jul 1815
William John Caley/ Isab Corkill Parish Church 13 Jun 1818. Private baptism
Patrick John Caley/ Isabella Corkill Parish Church 26 Nov 1820
Edward John Caley/ Isabella Corkill Parish Church 2 Feb 1824
Margaret John Caley/ Isab Corkill Parish Church 29 Apr 1827.

Maughold M.I.s could help with the two John Caley/Isabella Corkill families - this John Caley, above, possible burial Maughold on Jan 8 1832, and also his son John Caley buried Maughold June 30 1872.

Isab CALEY aged 62 buried Maughold Sep 8 1843.
1841 census Maughold:
1 10 42 Ballakilley
Isabella CALEY 60 Ag lab Isle of Man
William CALEY 20 Tailor Isle of Man
Margaret CALEY 14 Isle of Man

I had a look at the other 1841 census and there is a scribble over the first letter of ?ailor, which we now know should have been Sailor, but William's occupation in the one above definitely looks like Tailor.
