https://familysearch.org/pal:/MM9.1.1/FPYL-FVCProbably just a co-incidence as this couple show in Scotland for 1881, but no John showing on the listing unfortunately:
Stephen King 50, Plater'S Lab. In Shipyard, b. Ireland
Mary King 46 b. Ireland
Laurence King 14 b. Ireland
Mary King 8 b. Ireland
Thomas Meallie 48 lodger, b. Ireland
Laurence Folan 26 lodger, b. Ireland
Address: 54 High St, Dumbarton
This couple show in Dumbarton right up to 1901.

PS: I am guessing the 1911 census entries didn't provide any clues of place of birth in Ireland....
