She is down as a Labourers wife, so he could have "wandered" anywhere - tunnelling, canal building etc or simply mining

Instinct says a "hot spot" for ROWSWELL would take you to the Somerset coal fields around Midsommer Norton, which would give a possible mining link.

National Probate Calender

Thomas ROWSWELL - Probate date : 24 June 1871

Adminstration of the effects of Thomas ROWSWELL late of St Briavel's in the Township of West Dean in the County of Gloucester, Labourer, who died 26 June 1870 at St Briavel's was granted at Gloucester to Caroline ROWSWELL of St Briavels, Widow the Relict. Effects under £100.

Read the Inquest Report - sounds awful!

No ROWSWELL's on the Gloucestershire Baptism Index from 1813 - 1837

One Marriage at YATE

Henry ROWSEWELL married Ann FLETCHER - 4 September 1837

There are ROWELS/ROWLES listed on FOD records - inc Henry ROWLES - Shoemaker

I don't have any information on Thomas I'm afraid, but I believe his daughter Miriam (Mary?) Rowsell/Rowswell married my 3xgreat grandfather, Edward Burley c.1865 in the Baptist Chapel, Chepstow. Don't know if this helps at all?
