Helen, I have Roxby's in my line. Your Margaret Jane Roxby's father's name is John She married a Yeoman Readman in 1878. That marriage certificate is available at the Bishop Auckland office or you can send for it at http://www durham.gov.uk/gro/search.nsf/search?openform. The 22nd of December 1888 she married 38 year old Thomas Walker, son of John Walker. That certificate is available at the Peterlee office or you can order at the same website as above. I have a different Margaret Jane Roxby (father Robert F.) in my line and not this one but not to say that somewhere on that tree your branch might be sticking out. Should you find that her father John Roxby is a brother to Edward b. 1798 in Washington, Co. Durham, then look me up again. Janis
