I think this is the one - he did have a wife Maggie and son Robert in Peterhead but they did not travel with him as I have their details.
The last I can find for him is the one you have posted - after that he disappears.
I think the Augus Comrie may refer to another from Peterhead - Comrie Angus and the surname may have became mixed up with Christian name.
I thank you for your help but it looks as if he will remain a mystery.
