I have also been searching for Hugh - he is also my father! I was born in 1947 and my brother Christopher in 1951. Our mother was Lorna Bruce Jones (nee Fielding) and after her death we were unable to find any record of her actually having married Hugh. We lived in Sussex and my parents separated when I was five (around 1952 I suppose)and we had no contact (as far as I know, as my mother would never talk about him, apart from the fact that he had been thrown out of the merchant navy when he went AWOL in charge of a ship in Helsinki) after that. According to my mother he had a drink problem. I have a few photos of him.
I found out a little via Ancestry about his previous marriage, and the fact that he had died in New Zealand.
I would love to hear from you.
