This is a long time after you posted this message, but I will give the information I have:
My ancestor Jane Horne(1796-1865) daughter of Alexander Horne & Cecilia Duncan - married William Tomison (1790-1832) (q.v.) on 19-12-1815, presumably at St. Mary’s Church.
In the 1851 Census, the record shows that Jane’s daughters Jane and Mary and sons John and Charles are no longer at home, but that daughter Margaret and son William (now “landed proprietor”) are still with her. Also at “Dundas House” in 1851 were Jane’s nephews, William and Thomas (both described as “scholars”) (probably children of her brother, James) and her niece, Mary (daughter of her deceased brother, Alexander and his still-alive wife Michel Thomson).
According to a letter from John Tomison of “Halcro” (1909) and to information from John Halcro (1974) William and Margaret may have been accompanied by or followed out in 1854,(to New South Wales, Australia) by Jane, her children, Margaret, Charles and Mary and her niece Mary Horn.
