Well I have marriage certificate for her I think. However her father is put down as Arthur Architect. Her father is Richard Arthur Architect so it must be her because people with the name Getrude Bullivant are not thick on the ground and I can't find any other Arthur that's an architect. All I can think is that he wasn't at the Wedding which is strange because she was underage at the time as she was 20 and the marriage was by banns not special license. Her grandfather was Richard and her cousin so maybe he called himself Arthur and she didn't realise his first name was Richard. What do you think?
