Hey there! sorry it took me so long to see this.
That must be him as my grandmother was Hilda, had a son named Ronald Ernest with Ernie. and then she remarried a fellow named Jim (Haswell?).
As far as I know Ronald was the only child. I would very much like to track down his other children (my half siblings - Peter? Caroline?)
I was born in Sunderland but now live in Vancouver BC.
would like to hear more from you firstname.lastname@example.org
all the best,
