[Éadríc]

Hm?

The standard, nominative form of the name in Middle Irish was Sitriuc, whereas Sitric is modern and in the genitive case.

As for his byname, here is part of the paradigm:

árchú ‘warhound’
int árchú ‘the warhound’
árchon ‘of warhound’
ind árchon ‘of the warhound’

Old and Middle Irish bynames need no definite article (i.e. no equivalent of 'the'), so Sitriuc the Warhound is simply Sitriuc Árchú, just like Áed the Black (i.e. Black Áed) is simply Áed Dub.

Yes, that I knew. I actually didn't mean to type it as "Sitric".

That isn't always the case. May be for this epithet, but definantly isn't the case 100% of the time.
