Well I got my reply today and good news, despite me giving the wrong address - I said Dulverton Avenue, Coventry and it turns out my aunt and uncle lived at Birchfield Road, Coventry - I now have the National Registration Number (don't know if that is any use to me) and the date of birth of my uncle which is what I wanted. The info also included their occupations, interestingly my aunt's is shown as "Unpaid Domestic Duties".
Now all I have to do is find someone with the same Christian name as my uncle and the same date of birth
I know that the surname they used was not his, but was one of my aunt's given names and was the maiden name of her mother.
