What is the connection?

River Thames

Probably the M4 as well.

I wish it was that easy but the connection is/was something specific between these four counties. I wondered if there was a link perhaps to Christmas (with the quiz being set at that time of year) but have googled absolutely everything but cannot find a specific connection!

It could be an historical figure or politician.

For example Kemp's nine days wonder would link London Essex Suffolk and Norfolk. It could be something like that.

Just googled this question.

"What famous person lived in Surrey Buckinghamshire Gloucestershire and Wiltshire?"

Two results may be of interest, one concerns noble families, the other gypsies.

Nothing jumps out though, sorry.
