Monsieur Montréal
Klondikes...Bill, Kate, Jake
Johnny England
Mississippi Mauler
Leon Arras
Eric Leyland (guess who's scraping his barrel again...)
Isha Israel
Boston Blackie
Yorkshire Kid (Hack knows a wrestler ...)
Roy & Tony St. Clair
The South London Tough Guys
The Liverpool Skinheads (Terry O'Neill becomes the first two appear three times on these lists.
Jack London,
The Wild Man of Borneo
The Lincolnshire Poachers
Le Bourreau de Béthune
Mike Dallas

The Bengal Tigers
Kendo Nagasaki
The Hungarian Horsemen

The following subsidiary list will yield a lot more, I'm sure:
Wrestlers' Geographical Bylines
The Polish Eagle (Johnny Czeslaw & Vladimir Waldberg,)
The Butcher of Budapest (Josef Kovacs)

The Cockney Kid (Tony Scarlo et al.)
The Russian Lion (Hackenschmidt)
The Terrible Turk (Ahmed Madrali)

As usual, all must have wrestled in the UK.
Any more?
