Hi, I have checked all my sources found all of John and Janes children christenings, but did notice there are two spellings for Kenyon also Kennion, two children were recorded to each spelling of Jane Kennion/Kenyon ...so be careful on further searches. Sadly I could not find a Manx marriage of John and Jane, there is a possibilty they married in England before 1839. Try Cumberland first i.e. Whitehaven, then Liverpool. I have no Kennion / Kenyon sources, but try the I.G.I web search site at www.familysearch.org it would prove Jane place of birth or christening. There is a wealth of information available at the Manx Museum in Douglas and the staff are most helpful. The children should be on the 1871 /81 census's for Liverpool, if not married by then.
