Cuthberga combines the Old English cuth (known, famous) and burh (fortress). Saint Cuthberga (d. c. 725) was the Anglo-Saxon abbess and sister of King Ine of Wessex — founded the great double monastery at Wimborne Minster in Dorset.
Her foundation became one of the largest Anglo-Saxon nunneries.
Cuthberga reduces to two — the number of Anglo-Saxon abbess.
