Married in 1847. This makes it unlikely that he is the son of James of Camus who was baptised in 1830, unless he was baptised as an infant of a few years, otherwise he would only be 17 at marriage.
BB: This is the James Gray who married Elizabeth Jane Dickson. His birth is alot earlier than I thought.
