I think the most likely death (assuming he died within the area of Monmouth RD, which is where they were in 1841) is James Charles Q3 1847 age 34. There is a brief mention of a death of a James Charles on 3 July 1847 "of paralysis while at work on the Skenehill, clerk to the Rev Thomas Price" in Monmouthshire Beacon 10 July 1847. Could be the same one.
