General Notes

"William Quarles of Ufford, nobleman, descended from the Vrijheeren [Vrijheeren = freemen, lowest level of the aristocracy] of the Barony of Quarles -- which lay in the county of Stirling in Scotland. They w ere recorded as living there in 1124 during the reign of the Scottish King David I, toward whom they stood in no little influence. The Vrijheeren of the Barony of Quarles were distinguished as royal diplomats seated in Edinburgh, as their contempo raries have noted.
William Quarles left Scotland in 1420, and was able to establish himself in England, in Northamptonshire, where he married Catharine, heiress of the ancient House of Ufford. During the reign of Edward I (1272-1307), the Uffords were called to hi s Parliament as Barons, and under Edward III (1327-1377) were Dukes of Suffolk. Some of this family became Under-Kings of Ireland.
"William Quarles, who through his marriage had become heir to his father-in-law's Ufford estates, took his name for himself and his descendents. Among these, some kept the additional name of Ufford, while others eventually bore only the name Quarl es. He died during the reign of King Henry VI (1422-1461)."
The East Anglian says that William of Ufford was of the time of Henry V which was from Mar 21, 1413 to Aug 31, 1422.
