On his blog Wulfhere's Devices, Calontir herald Wulfhere of Eofeshamme offers help on researching English and Anglo-Saxon names and personas.
Wulfhere of Eofeshamme writes:
Here are some online resources to help in developing a name for your English or Anglo-Saxon persona in the SCA. Online resources are generally searchable making it easier to locate a name. You may still need to pick up a book to document an Anglo-Saxon or English name for the SCA, but these sites will generally point you to where you can find a name in print, and in some cases the sites themselves can be used for documentation.
According to the Falcon Banner, Wulfhere is also seeking suggestions for additional links.
