Leofwynn

Leofwynn of Bishopstone also known as Lewinna or Leofwynn, was a 7th-century female saint of Anglo-Saxon England, floruit 664–673 AD. She was active under King Ecgberht of Kent, and died in 669 AD.

In 1058, a monk named Balger, from the Flemish monastery of Bergues, travelling by boat down the coast, was blown into nearby Seaford during a nocturnal storm on Easter Saturday, and stole her reliquary from the local minster church (perhaps Lewes).
