Searching for any help with a John Davison (sometimes spelt Davidson) born in Ireland around 1813 who appears in the IOM 1851 Census with wife Eliza, born Ireland 1806, son John, born Ireland 1838 and sister-in-law Mary Wilkinson, born Ireland 1803 (a widow). John was a nailer. He and Eliza figure in the 1861 and 1871 IOM Census (by which time he is a Grocer) and they died in Braddan in 1881 and 1880 respectively. Son John had moved to London and put the administration of his father's estate into the hands of his cousin William Kelly of Douglas.
Any clues would be most welcome.
