I have found one of the other census records I put on the BB in reply to Bob. Was this your William CHRISTIAN (1822 – 1885)?

1851 census German, at Close E Gary.
William Christian aged 29, Farm Labourer, b.Maughold, and his wife Ann aged 28 b.Michael. Also children William aged 5 Robert aged 3, and Ann aged 1 b.German. Also mother-in-law Ann Boyde Widow, 55, Herbalist, b.Michael.

Frances replied:
Ann Cannell born 1768 married Robert Wade born 1760 in 1790 in Kirk Michael ('both of this parish' in Register) buried Michael 23 March 1844 age 76, and her daughter Ann Boyde nee Wade described as 'herbalist' in 1851 when living with her dau and son-in-law Ann + Wm Christian) carried on her trade.
several refs on MNB.

Also finally found the census record I posted for father Robert. I wrote:
"In the 1851 German census there is a Robert Christian b.Maughold living in Poortown with wife Agnes and small child, next door to Philip Barr & family (prob Margaret Boyd's son - Margt Barr's brother). And with Wades on the other side.
See the 1851 census for Robert Christian and family (on this BB - previous message) to compare.
This looks like the same route the Auckland Christian family took with their information which they sent to Bob."
