Penda of Mercia
Kyneburga (d. c. 680) (also called Cyneburh in Old English); the name being also rendered as "Kinborough" and in occasional use as a Christian name) and Kyneswide (Cyneswitha) were sisters, the daughters of King Penda of Mercia (who remained true to the Anglo-Saxon religion). She was eldest daughter of Penda. Although her father was an opponent of Christianity, she and all her siblings converted.
