I have a Mary Ivison born Bolton or Bolton Gate, Cumberland in 1824 who marries in 1854 a Christopher Wannop born 1824. I have census for them but I am missing census for her for 1891 which would be as Mary Wannop. I have not been able to determine her census items for before her marriage. She is residing with her daughter Frances who marries William Percival near the end or her life. Would really like parentage and grave site but any help appreciated?
