I have a Henry Allan Banks b Bet. 1843-1844, m Mary Horne Tomison, b 1830 d 1878-1881. I have some family history - where he is described as "of Smiddybanks" - there is an 1881 census entry for such a family.
Though I must admit I am worried about the discrepancy in birth date, though my source claims this link from a 1909 letter.

I think we may have a link! I go back another 2 generations of Tomisons. Interestingly, Mary's Grandmother is Margaret Rosie, and one of their domestic servants is a Jane S Rosie. Her Mother is Jean Horne b 1795-1796, d 9 November 1865 at the Hope

I'd love to share more data in this area, and tie this down once and for all!
