Oswine of Kent
Oswine is known from charters: one  is dated 26 January 690, witnessed by Swæfheard, and implies Oswine's descent from Eormenred; and a third , which is undated, but again witnessed by Swæfheard, expresses Oswine's gratitude for his restoration to the kingdom of his fathers (gratias refero miserenti Deo omnipotenti qui confirmauit me in regno patrum meorum et dedit mihi domum cognationis mee).
After the death of Eadric of Kent, Kent was in turmoil. Cædwalla of Wessex invaded in 686 and installed his brother Mul of Kent as king. Mul was killed in an uprising a year later. Cædwalla returned and laid waste to Kent leaving it in a state of chaos. He may have ruled Kent directly after this second invasion. However, he abdicated in 688 and went on a pilgrimage to Rome, possibly because he was dying of wounds suffered while fighting on the Isle of Wight.
Oswine was of the royal house of Kent. Gordon Ward, writing in Archaeologia Cantiana suggests that Oswine was a grandson of Eormenred of Kent, possibly the son of Æthelred of East Kent. A charter of January 690 granting land in Sturry to Æbba, abbess of Minster-in-Thanet states that they were closely related ("carnali propinquitate proxime"). It also indicates that Oswine had the support of Æthelred of Mercia.
