Is hubby's grandfather a Peter Cairns showing as born Greenock and living in Sunderland in 1911? His birth year there is showing as c. 1866. As you know, census ages can be unreliable.
Have you been able to find Peter's marriage (was it to Annie Fordy in 1903 in Sunderland?) as at least this would let you confirm his father's name.
There is only one Peter Cairns showing on IGI as born in Greenock anywhere near his birth year:
PETER CAIRNS Birth: 29 AUG 1862 Middle Or New Parish, Greenock
Parents: JOHN CAIRNS and MARY RILEY
One other child shows as born to this couple, Joseph in 1859 Greenock. I am wondering whether this is the family in 1861 before Peter was born. This is messy transcript as you can see:
John Cairus 42, Musician b. Ireland
Mary Cairus 40 b. Ireland
Bridget Cairus 18, Cotton Mill Worker b. Ireland
Elizabeth Cairus 12 b. Greenock, Renfrewshire
Joseph Cairus 2 b. Greenock, Renfrewshire
Address: Split Close, Greenock Middle
