That's absolutely brilliant, Mike. Not only Florence's burial plot reference but a child we didn't even know about and a new name for her mother which she never appears to have used on any official document in her lifetime, preferring her middle name.
A wealth of information!!
Just found out that it would appear Florrie Fall (DOB 26/11/1917) grew up a Roman Catholic as that was her aunt's religion. So is there a way of checking the Catholic records to see if there is anything there? It's a father's name I'm particularly looking for (more particularly to check if it was actually Florence's soldier husband Harry Fall that was the father).
Thank you so much for the help so far. It's been great.
