Cymenshore is traditionally thought to have been located at what is now known as the Owers Rocks, south of Selsey, however there is no archaeological evidence to support the existence of Ælle and his three sons in the Selsey area.
Cymenshore arvatakse olevat olnud kohas, kus nüüd on Owers Rocks Selseyst lõunas, siiski ei ole siin arheoloogilisi tõendeid toetuseks Ælle ja tema kolme poja olemisest Selsey alal.
