I believe this is William Vaughan christened 1830 in Hay, Breconshire, and who died before 1881 when his wife Elizabeth (Betsy) is listed in the Llanfoist Census as "widow." It appears that he was engaged in dredging the Brecon and Monmouthshire Canal and not in the illegal activity.
John and Elinor's first-born child, that we know of, was named William. He died in 1823. It was a common practice to name a child after a sibling that had already died. In fact, John's uncle William (1768-1851), who we believe may have trained him as a butcher, was the third William in that family after two others died as infants.
