Thanks for your guidance @DisappointedReader.
This is probably bit of a damp squid squib but here's details from the marriage certificate.
Timothy Ronald Walker was a Plasterer from Burton on Trent, and that his father was a Master Plasterer - as we know. I raise an eyebrow at the idea that he went to university before becoming a Plasterer in the family business.
Sally Ann Winn was a Clerical Officer from a farm in Dunstall, Burton on Trent. Her father was a Farm Stockman.
Clerical Officer suggests a Civil Service job, which fits in with working in a law court. It was quite easy to get into the Civil Service in the 80s but some basic qualifications were required - I joined the Civil Service in the early 80s and some O Grades were required in Scotland. Presumably it was the same in England (GCSEs/O Levels).
As all parents are named, including mothers' maiden names, her pen name is on the certificate, albeit the wrong way round.
Age on marriage were 25 for Tim and 23 for Sally.
