You could try a director search at companies house, if you think he might have been involved in a project.

Try find them on social media...then ask

Find his wife, children, people with the same name and look through their photos for your friend.

When you find his photo, send a message to the relative.

There's a chance he has a Gmail account with a guessable name. Try some out on Google sheets, hover the cursor over the cell where you inputted the email address and if his photo pops up, you've got yourself a match

Are his parents local? Do any of your mutual acquaintances know where they live?

Could always put a pic up here of what you have. Someone might be able to work it out. If I can read my boss' writing, I'm happy to give it a look lol. PM if don't want it shown publicly.
