That William Henry Christian is very interesting, Len.
There were many William Christians around the right age, but only one William Henry that I have found, bapt in Maughold on 12 July 1852, one of the eight children of William Christian and Eliza Cowin. In the 1861 census father William aged 52 b.Lonan was farming 70 acres at Folieu Farm Maughold, with wife Elisa 41 b. Maughold - all the children b.Maughold.
If this father turns out to be the right one in William Henry's marriage cert., and William Henry the right person, there will be far more details of the family in Maughold records.
