Thanks Sue. Now I'm annoyed with myself that I didn't think of checking John's marriage to Jane - I was so busy concentrating on Ann that I must have assumed the same details would be on Jane's registry entry. I had looked up my father's ancestors & was pleased to find all details there, parents, occupation, parish, marital status & solved many loose ends with the German marriages & remember saying that Malew Parish had poorer info.
If John Kelly was actually 38 & not 28 in the 1851 census that puts a whole new twist on things! His marriage to Jane Ritson could even say how old he was at the time of his marriage which would solve his birth year. I wonder if I write to the lady at the Peel library of iomfhs if she could check for me. Bit cheeky but our next visit to IOM could be ages.
