Edburga combines the Old English ead (wealth) and burh (fortress). **Saint Edburga of Minster (d. 751)** was the Anglo-Saxon abbess, daughter of King Centwine of Wessex — succeeded Saint Mildred at Minster-in-Thanet. A noted scholar, she corresponded with Saint Boniface in Germany.
Distinct from Edburh, the wicked Mercian queen who killed her husband.
Edburga reduces to four — the number of Anglo-Saxon scholar.
