 Eadbald died in 640 , and according to most versions of the Kentish Royal Legend was succeeded solely by his son Eorcenberht . However , an early text ( Caligula A.xiv ) refers to Eormenred as ' king ' , suggesting either he was a junior king under Eorcenberht , or had a shared kingship . One suggestion is that the some other version of events in the ' legend ' , which give him no title , may have been an attempt to discredit royal claimants from Eormenred 's line .
