There is evidence for a British influence on the emerging Anglo-Saxon elite classes. The Wessex royal line was traditionally founded by a man named Cerdic, an undoubtedly Celtic name cognate to Ceretic (the name of two British kings, ultimately derived from *Corotīcos). This may indicate that Cerdic was a native Briton and that his dynasty became anglicised over time. A number of Cerdic's alleged descendants also possessed Celtic names, including the 'Bretwalda' Ceawlin. The last man in this dynasty to have a Brittonic name was King Caedwalla, who died as late as 689. In Mercia, too, several kings bear seemingly Celtic names, most notably Penda. As far east as Lindsey, the Celtic name "Caedbaed" appears in the list of kings.
