I have a Mary Ivison born 1824 Bolton, Cumberland who married Christopher Wannop born 1824 Stanwix in 1854 in Carlisle. I have census for her as Mary Wannop for 1861, 1871, 1881, 1901. In 1901 she resides in Rockcliffe with her daughter Frances and son in law William Percival. One census also contains information for a related Thomas Iveson residing with the family. It is very possible that the Rockcliff families could be connected.
