Hi Dave,
Actually he lived right on the south coast at Beaulieu, so it is certainly possible, although 3 consecutive censuses list him as Ag Lab, and he was never absent at sea on census night.
Certainly something new to think about though . . .

Edna, you may be right . . . could it be that he was ashamed of his father's lowly status perhaps, and changed his occupation?
Thomas himself was a shipwright, possibly apprenticed to his maternal uncle in the early days, and seems to have been quite "upwardly mobile"

Mike.
