Hi Paul,
I came across your Blacknell history recently, and have been overjoyed by the find.
My maiden name was Blacknell. I was born in St Asaph 1962. My father is Ronald Blacknell, my grandparents were Frank and Freda Blacknell. I have an older brother Philip Blacknell, born 1959.
I’d be happy for you to get in touch if I can be of any help.
Judy
