Interesting Whitehouse. The Celts were driven to the fringes of Europe by the Romans to Ireland, Wales, Scotland, Normandy, Brittany and Basque Spain and France. It makes me wonder if their refuge included the swamps of Friesland. Wikipedia history has not mention but it does note that "These wars [Frankish conquest in 8th C] benefited attempts by Anglo-Irish missionaries [[which had began with Saint Boniface) to convert the Frisian populace to Christianity. So maybe the missionaries brought the game there.

I found a couple of interesting side notes while looking this up, "As both the Anglo-Saxons of England and the early Frisians were formed from largely identical tribal confederacies, their respective languages were very similar. Old Frisian is the most closely related language to Old English and the modern Frisian dialects are in turn the closest related languages to contemporary English.

Also Peter Stuyvesant of New York fka New Amsterdam fame was a Frisan. Also claimed are Mata Hari and Jane Fonda as a descendant.

As for our tournament the weekend, mother nature was in a different [or indifferent] mood. Rains made the courts unplayable so the tournament regrettably had to move indoors and 4-wall.
