as far as I know I have all the BMD stuff (unless I've missed anything due to incorrect data or children born abroad or out of wedlock etc.) but I'd like to get in touch with relatives if possible (children/grandchildren of the above) as there are some gaps to fill in, and I'd really like to put some names to some of the faces on my photos if possible. I'm also keen to find dates for people I don't have them for, due to probate/death records being unavailable, etc.
Apologies for sounding vague!
I've used the 1939 register to find birthdays for a number of people across my family trees. Thank you for the suggestion, though.

Basically I just want to give it a bit of polish. Middle names, birthdays, etc.
