Thanks for clearing that up Frances. Easy to have a misread.
It seems I may still have a gap in my records, though - the only Patrick I am aware of at that time I understood to have married Mary Quiggen (9 Jun 1784 KM) but as the nearest Patrick Corjeage baptism in Michael is 1732 he would have been 52. His 1802 Will (1802 A 63 Michael) leaves everything to his wife 'Mary' and there is no mention of any children. Mary wife of Patrick died in 1824 and I am not aware of any will for her.
The only Gell/Corjeage marriage I've turned up so far is not until 1824 KM - Henry Gell of Patrick & Ann Corjeag. It seems I've found even fewer Corjeags than I thought!
Thanks for replying.
