Hello Len. I think what you have here (re: 'William Henry' Christian) is most likely to be the one I'm from. How the 'Henry' was derived is a wonder, however all else seems in accord with the little I know eg the children etc..
I vaguely recall a reference by my father (Harry Brian McComish) that Martha Jane (my great grandmother) lived with her uncle (a Wilson?) who may have been a proprietor of a hotel in Wellington, NZ.
Regards
Harry
