Gilbert Christian is currently connected as the son of Patrick Christian and Mary Nettles. Patrick married Mary in 1683 in Ireland, and Patrick died in 1687 in Ireland giving them a four year window to have any children. There were only two children mentioned in Patrick's will (see his profile), William and Mary.
From Gilbert's profile, he was either born in 1677 in the Isle of Man (from his birth date/location fields) or 1660 in Scotland (from his biography). Neither date/location combination has any sources. His biography does not mention any parents.
I propose that unless there are any reliable sources for Gilbert being the son of Patrick and Mary, that he is disconnected from them. I also propose that the Southern Colonies Project adopt and Project Protect Gilbert's profile to prevent these parents being reattached.
