I've drawn a crude chart for the benefit of anyone tracing this line of Christians. Data is taken strictly from A.W. Moore's "Manx Families, 'Christian's of Milntown, Isle of Man and Ewanrigg Hall, Cumberland'" which can be found on Frances' site at http://www.isle-of-man.com/manxnotebook/famhist/families/awm1889/chrstn_m.htm.

My chart is here:
