Irish Gypsies are Travellers (and their bareknuckle fights vide "snatch" movie) , they are not the Romani Gypsies. First have Celts/Irish ancestry, second come from India.Romani wrestling traditions are awesome.. The bare knuckle fights we still have and the gypsy fights of course.
I really doubt if Romani(Roma) have any wrestling traditions - there was quite a lot Roma/Gypsies in my neighbourhood when I was a kid in 80' in Poland and they have no connection to any kind of sport. Dance, singing, palmistry, thievery, begging but not sport. Later in 90' tens of thousands of Roma/Gypsies from Romania came to Poland (Romanians do not like Roma at all) and they all were thefts and beggars.
There is quite big minority of Roma in Slovakia and Bulgaria and they live in ghettos which look like poorest brazilian favelas or african villages (Roma were forced by communists in East Europe to abandon their nomadic lifestyle and live in the cities/villages).
Nobody here have ever heard about Roma wrestlers.
