Hi Richard,
Wow, I have been searching for my birth father for many years and I do hope that at last I have found some answers. I have researched his ancestors who came from Hutton Bushell near Scarborough and have found lots of info regarding them including many bmd certificates but, alas, have been unable to find any whereabouts of my father, after his first marriage.
My father's father, also John Hopper, came from Cheshire but my father, as I told you before, was born in Leeds.
Eagerly looking forward to hearing from you,
John H
