Sorry, when I say birth certificate, I mean one of the children born in Wolverhampton.
If you are able to search local Baptisms, they may show Rosanna's maiden name, otherwise, the civil birth certificates would be the order.
I did search in quite a few ways on and off and on this occasion it might have been Ros* in Wolverhampton. Using * is often useful.
I then looked through possibilities and you can see how the name was misinterpreted.
Other tips are just by first name, surname, place of birth etc.
I also looked at Free Reg I think, and sadly, I think there are deaths for Ellen and perhaps young James.
