13 December -- St Edburga of Minster-in-Thanet
St Edburga, as so many of the sainted Anglo-Saxon abbesses seemed to have been, was of royal birth. She died on this day in 759.
There are a few other Edburgas who merit a write-up on the internet but there is a short life of this one here. There are some propers apparently in the Anglican tradition here, though the author doesn't give his source.
