It is possible that it was customary among the Mercians until this time for there to be more than one king, and Penda and Eowa may have ruled over the southern and northern Mercians respectively.
É posíbel que fose costume entre os mercios até ese momento que houbese máis dun rei, e que Penda e Eowa puidesen gobernar aos mercios do sur e do norte respectivamente.
