Wow! Mary Elizaeth Padley watson was my great great grandmother through her first husband, Victorian architect Gustav Joachimi. I think they never divorced--and she also was "married" to another man in-between him and Watson. I have the marriage certificate--she called herself Marie Joachim when she married Watson. I think she was quite a few years his senior. He did father others. I have the documents (and a photo of BERYL AND MARIE) on my ancestry site, which is public. I did not know that Beryl was not her natural daughter but it makes sense because of Marie's age. She and Andrew did have twins, one of whom died as an infant (Donizetti)and the other, Beryl's brother Norman, I also have a photo of. I would love to share more with you--I have an orginal painting done by Andrew in my family.
