Turk in 12th Century England

Toni,
While googling the name "Richard Turk," I ran across a site titled "A list of Priors and Grand Priors, Order of St. John of Jerusalem. Jurisdiction of England or the British Isles." I have included the list at the bottom here. Richard Turk was the third prior, serving from 1165 to 1170 A.D. The order was apparently some kind of international Christian knightly social service group organized to help the poor. It was Catholic in this Richard's time. I don't know whether or not it opened up to Protestants during the Protestant Reformation in England. The group still exists today and apparently supports hospitals, etc. It was organized in England in Kent County, where one cluster of Turks of English background originated.

Google: "Jurisdiction of England or the British Isles" to find the list. The website address for the whole colorful site is www2.prestel.co.uk>church/oosj/priors, but I had trouble finding the prior list itself that way.
