Italy1944, are you looking for living descendants of Hugh Dorrian?
If so, I don't know if these are relevant, but there are two births on Freebmd with surname Dorrian and mmn Wright.
A male born in 1946 in Chester district and a female born in 1950 in Huddersfield district. The Chester district seems to fit with Hugh's marriage in 1945 and his wife's parents living in Handbridge.
As we are not allowed to mention names of those living or possibly living, I have not mentioned any names, but they can easily be found on freebmd:
https://www.freebmd.org.uk/cgi/search.plI had a quick look but couldn't see a death for his wife. She may still be living, and you may be able to find her via electoral rolls. To my knowledge you have to pay for this information. There used to be a free site which allowed limited lookups but the link I have is broken.
