Oliver
Simon
Ben
Dominic
Stephen
Stuart

Ed is definitely missing from the lists so far too. Loads of Eds in their 40s.

Loads of Tom, Ben and Dan!

Ben, Dan, Scott, Alex.

Most of the others mentioned already were in my class at school and uni. I'm 57.

Matthew, Christopher, Andrew, Richard, Luke, Ben, Johnathan, David and Nicholas were very common names in my year group (I'm early 40s).

Richard. Very popular is the early 80s

These are the ones I know, Stuart, mark, Chris, Tim, Glenn, Daryl, Richard

They're either called James or Paul.

I can't see it on anytime else's list, but Gareth is a very common name for men of that age.
