I don't know the answer to your question but maybe with some extra info. such as where he was at later dates & when, may help us?
Do you have him on any census records, did he stay in Scotland or did he immigrate?
If you can add all you know it will help others to help you.
For what it's worth...
I would need to check back on SP but I have an ancestor recorded as born 'Beith' & if I recall correctly it was Beith, Fife which wasn't the case as it was Beith, Ayrshire!!!
I spent an absolute fortune trying to locate the birth (pre the free index)!!!
If you can't find your ancestor in Fife then Ayr would be the place?
Where did Robert marry, who did he marry, who were his children & what info. do you have to date please?
Add all you know to save researchers going through info. you may already have.
