Interesting point, I haven't seen the marriage certificate but will look for this to check if there is a Father's name. I don't know if she ever referred to her as her Mother, whenever it came up in conversation she was called by a sort of nickname, which was her three initials – DBF
Yes, it would seem like the Father may have contributed to her care but I don't really know where to look to find this information. That would certainly give me the link to connect them all together but for now it's well and truly missing!
I've only just found the Brighton connection, but didn't know about the street indexes, that will be interesting to follow up on, thank you.
Re the Father the only thing I have is the name of a man living at the same address as was given as the address the birth Mother was living and working at, which I found on the electoral roll. There's no proof he was the Father, he did leave that address shortly afterwards, but that could have been connected to his work rather than anything personal, I just don't know. I don't mind giving you his name but that's really all I've got – can you do anything with so little information?
