The info I posted on the first birth registration was from a digitized copy from the GRO, see attached.
In a formal adoption, there should be an indication on the original. There is nothing. Mind you, an amendment should have been noted.
Audrey has two registrations as well, amending the name of her mother.

I think some of us are thinking, at the moment, that there may not have been a real adoption, the child was a result of an affair with Mr Forrest, and given to Forrest to raise. As to why keep Audrey; I think it would be much harder to part with a child you were raising, especially when it ties your husband to you, as opposed to a baby that might end your marriage Just my thoughts... nothing concrete as of yet. People attracted to the life of adventure, fame and fortune, have a different mindset than us "regular" people!
