Hello.
Yes, you assume correctly.
The first indication that Joseph was a Boatman was on his sons baptismal entry in Tettenhall Parish Church in 1831.
and from then onwards he and his Family always gave their occupation as Boatmen .........
They moved about a lot Mitton, Tipton, Worsley and Tettenhall. [although to settle is not really what they did , they sort of holed up for

? the night/day and then carried on moving.]
I have them as a family on the 1851 Census in Tipton, but have not found them there in 1841...so wondered if they were in the Wolverhampton area.
