I found out that my 3rd great grandfather George Bowman moved to the IOM to become a post office clerk at Douglas. I found this on the 1851 census records. I love how they put his place of birth as "England!" It also says on this census that he was married to a Hannah (aged 27) with three children: Ann, George & Mary. As I haven't been able to find a likely marriage on mainland UK, I was wondering if there was a marriage record for them on the IOM. George's parents were George Bowman (1790-1861) and Ann Clark (1791-1869). The marriage is likely to have taken place between 1841-1851 (sometime between the two census records).
Many thanks, D.
