I have just spent an hour on the ph. with my Mom. She would give me names and dates, and I would type them into the FamilySearch.org . I think that your Great, Great Grandfather, Hugh Squair and my Great, Great, Great Grandfather Robert Squair were brothers.
Their parent were Robert Squair b. August 1756 and Janet Ross. They were married 1772.
Robert's parents were Alexander Squair and Jean Lauder.
All the above were from Auldearn.
