Christian Milne (nee Bruce) is shown as a widow in the 1871 census, but as married in 1861, so it looks like Adam Milne must have died some time between 1861 and 1871. I can't see any obvious death of Scotland's People, but given he was a seaman, it's reasonable to suppose he died at sea.
I think the marriage registration is your best bet to track down his parents.
