Wow, Jen, that was very kind of you.
Now, interestingly, the father of the Ada we are looking for was a shipwright. Coincidence?
Can we find an Ada, daughter of Joseph? And mother Ada!
If not, maybe the names on the certificate are wrong!
I did come across an Ada O/Ada Olive Young, born Portsmouth, living in Wales, whose husband was called Charles in 1901, but was not called Charles in 1911.
Something strange about them, whoever they were I couldn't find a marriage. And then why would Ada Georgina call herself Ada Olive!
