I can't see any entries in the IGI (FamilySearch.org) for the IOM, nor any burials:
www.iomfhs.im/lawsons/burials/r_a.html (incomplete). If an IOM name you would expect to see some entries.
I think you may have misread the name in the 1841 census, because it doesn't appear in this index: www.iomfhs.im/lawsons/census/c41-r.html
