Hello Sophie, I hope you don't mind me contacting you, but I'm researching the Scott family on Ancestry, my tree is Ellis family tree
I have been unable to find Gavin Scott' wife Elizabeth Allan's death, I am sure she died between 1871 and 1877, the last date being her youngest son Robert's death, but where she died is a mystery, I have thought that she must have moved to live with one of her married daughters, maybe in England
Ann Scott, single person the sister of Gavin Scott, left a will and she died 1 August 1881 at 388 Duke Street Glasgow - her parents were William Scott and Janet Cunningham, I have no information on this couple other than Ann's birth which was 26 June 1797
this is the 1871 census for Ann

I hope this helps , - I have still a lot to look for with this family - it started with James Miller who comes down this line through his mother, James committed suicide in 1956, like wise William scott also died by Hanging in1886
