Thanks for your reply. I have no idea where he lived in Belfast, I'm afraid. I suspect he was low church but am not sure. His occupation when he got to Scotland was stated as wood sawyer/journeyman. I have tried church records with no success and the censuses seem to be too late - 1841/51. I did find a christening record of a Jane Hamilton (the name of Robert's wife, also born in Belfast) for 15/04/1819 St Anne's Belfast, parents William Hamilton and Jane, but have no idea if this is the right person.
