Medieval naming practices have been a hobby of mine for a
long time, so I thought that I'd add a few comments on
these.

<Kunnjátta> is the Old Norse respelling of Old Irish
<Connechta> '(inhabitants of) Connaught', so <Kunnjáttaborg>
would literally be 'fortress of Connaught'.

The byname appears in various forms in different
manuscripts, including <hreða>. Its meaning isn't certain,
but it may go with <hrœða> 'disquiet, disturbance'.

<Kerþjálfaðr> is an Old Norse attempt at Old Irish
<Tairdelbach>, which was pronounced very roughly
\TAR-ðel-vakh\.

Nominative <Kylfir>. I've never been able to figure out
what Old Irish name -- if any! -- underlies this one.

> Dungaður hét son Brjáns
> A son of King Brian was called Dungad

<Dungaðr> is for Old Irish <Donnchad>, which was roughly
\DOHN-khað\.

Old Irish <Murchad>.

Old Irish <Tadc>, pronounced like Old Norse <Taðk>.

<Kormlöð> is Old Irish <Gormflaith>, roughly \GORM-laþ\.

<Brennuna> is accusative singular, 'the burning'.

<Síðan er hún varð> is 'after it (= the burning) happened'.

Zoëga s.v. <fá> (12): <fá e-n til at gøra e-t> 'to get
someone to do a thing'. Gunnarr was chosen (or perhaps
persuaded) to tell the story.
