He is also in the 1881 census at 20 Thwaite St Barrow In Furness, Lancashire with his daughter and her family, but unfortunately no bapt for him in the Isle of Man (in the IGI). There were a number of Gordon families in the IOM, especially in Malew, but you need his father's name and occupation from his marriage to get further. His daughter was born c.1851 in Kendal, Westmorland, according to the census, which might help locate his marriage entry? You should be able to get his wife's place of birth from earlier censuses, and the eldest child's age should also help with the marriage date .
