can't find any match in bapts nor any obvious Robt in 1841 or 1851 IoM census (try www.imuseum.im for bapts etc) but there is a 1821 bapt at Braddan (parish includes Douglas) to a Thomas Hodgson + Cath Quinney (how certain are you of ages - if married a younger woman Robt may well have deflated his age) - they (but no Robt) can be found in 1841 and 1851 census - in 1851 at Derbyhaven with Thomas(born England) on parish relief - they married Braddan 18041218 (both of parish) tho the age of Cath in 1851 does not match any Quinney bapt in Braddan but does match a Cath d/o James Skillicorn + Mary Christian (Mary d 1800 there is will summarised on manxnotebook) - however I can't find a marriage to a quinney so just offer these as possibles
