Can you help track down Bryan or William (Bill) Chapman?

Can you help track down someone local on behalf of Dave Tavener, St Albans City Football Club Historian? With 356 goals in 362 games Wilfred ‘Billy’ Minter is St Albans City’s all-time leading goalscorer. In January 1985 he was laid to rest in an unmarked grave, 32-years on and that grave is still unmarked. Earlier this year a JustGiving page was launched to raise funds to have a headstone erected for the former England Amateur International. The page can be found here: https://www.justgiving.com/crowdfunding/billyminter But, before a headstone can be put in place permission has to be granted by the grave owner who is Bryan Chapman whose last known address was in Welwyn, Hertfordshire. Bryan, 88, has since moved from this address and we are keen to trace either him or his son Bill (William). Bill recently posted an article about Billy Minter on the Herts Memories website but left no contact details. We would be most grateful to hear from anyone who knows of the whereabouts of Bryan or Bill. If you can help in any at all please contact Dave Tavener via clarencepark@hotmail.com Thank you.
