I'm not surprised you are shocked! Trust it to be me to open this can of worms.......
I note that Isabella Rosina Wedge was born 2/6/1887, d.1970 Southwark.
The only way to confirm she is indeed the Isabella Rosina Williams born 1887 is by getting the birth certificate which would confirm birthdate. Father could be named as Frederick but as we know they weren't married possibly father's name could be left blank although I'm sure Frederick was her father. Really can't say but birth date would be the clincher.
Sorry to have put the cat amongst the pigeons.

Don't apologise! I think its made things truly interesting. I'm very thankful! I hadn't actually noticed before that I didn't have a birth confirmation as Isabella Rosina Deloche as I have instead got her birth information from her death certificate (of which I have an original copy of). Yes, she married Alfred Frederick Charles Wedge and so you have the correct death date.
Not sure if you've seen it already but I guess to easiest way of showing you all what I have so far is linking to my Ancestry tree.
http://trees.ancestry.co.uk/tree/19989976/person/879970978Yeah, I think I will have to get the birth certificate. Although it seems that in the Census Frederick may have been lying to make sure it looked like they were married (too much hassle to change kids names) and Isabella has been listed as Williams so that she doesn't stand out, I guess?
It does make me wonder if Isabella knew much about Johanna and Isabella as I guess she grew up with Rose as her mother figure. Definitely something to look into!
I will find the records you have found now and add them to the tree.
Thanks once again!
