Philip, considering the dozens of Corkills in Maughold at that time, it isn’t too bad. But it would certainly help you to get the wills.

The other family is far more confusing because as well as the Wm Corkill/ Cath Joughin marriage there were two marriages between Wm Corkill and Cath Corkill, with one at almost the same time as the Joughin one.
Having looked more closely at these families I’ve changed my mind about which Cath was Cath Joughin in the 1841 census:
3 1 4 Highbernian Cottage William CORKILL 30 Ag lab Isle of Man
[?William CORKILL 73 yrs Maughold buried Mar 25 1880?]
3 2 4 Highbernian Cottage Cathrine CORKILL 30 Isle of Man [I think JOUGHIN]
[Catherine CORKILL 83 yrs Maughold buried 14 Jun 1893]
Catharine d/o Charles Cannell/Cath Joughin 18 Jul 1830, Illegitimate.
3 2 4 Highbernian Cottage William CORKILL 6 Isle of Man
William s/o William Corkill/Cath Joughin 6 Feb 1835, Private baptism.
[William CORKILL aged 10 Son of Wm CORKILL buried Sep 23 1844]
3 2 4 Highbernian Cottage Daniel CORKILL 5 Isle of Man
Daniel s/o William Corkill/Cath Joughin 6 Mar 1836
3 2 4 Highbernian Cottage Cath CORKILL 3 Isle of Man
Cath d/o William Corkill/Cath Joughin 22 Jul 1838
In 1851, in Rhenabb, were Wm, 41, ag lab, Cathe aged 40, Daniel aged 15 apprentice shoemaker, Cathe aged 12, scholar, and William 3 months. [I don’t have full 1851 transcripts – just some Corkills.]
