I have spent months on this particular part of my tree, and I have eliminated most other Matilda Lawrences/Laurences that popped up when looking for mine. The problem is that I cant even eliminate this one because they do both, totally disappear after that 1891 census. No Mathilda Gutrolf/Gutrolg is anywhere, no children were born, no death, no travelling, nothing .... and add to the mix that My Matilda, who I know for sure was my great great grandmother had two children with my GGGrandfather, William Henry Pratt, and her name is quite clear on both their birth certificates, and on workhouse records, and her death in 1922 ........ but no marriage is to be found for them, on the 1911 census, when the entire family were in a workhouse in Dartford, she is stated as Matilda Julia Laurence, then Pratt added .... and "S" in her marital status, then crossed out and the "M" added ...... so I really don't think they married. I think they were a "rough" family, obviously very poor, and lived in the slummiest of "Sutton-AT-Hone" Swanley, and then the really "bad" parts of Deptford when they moved back. I would so love to crack this, and actually don't think I will ever manage it, so far no stone has been left unturned and I don't think there is any other avenues. My post on here was a desperate one!!
