No idea but they have been around for a long time.

Never heard of it.

"The French Defence is named after a match played by correspondence between the cities of London and Paris in 1834 (although earlier examples of games with the opening do exist). It was Chamouillet, one of the players of the Paris team, who persuaded the others to adopt this defence" - https://en.m.wikipedia.org/wiki/French_Defence
If you count the big one it should be an odd number
