Церковная история народа англов
Cearl (or Ceorl) was an early king of Mercia who ruled during the early part of the 7th century, until about 626. He is the first Mercian king mentioned by Bede in his "Historia ecclesiastica gentis Anglorum". Bede was a Northumbrian who was hostile to Mercia, and historian Robin Fleming speculates that as "ceorl" means "rustic" in Old English, his name may have been a joke.
