Rather, Congal and Blathmac were both sons of Aed Sláne (see e.g.
Charles-Edwards, Early Christian Ireland, 602-3).

The genealogy of the Fir Tethbae (O'Brien, CGH p 162) does include an Aed,
with a grandson Blathmac and a great-grandson Congal. But the Fir Tethbae,
the descendants of Niall's (probably imaginary) son Maine, are expressly
contrasted to the descendants of Niall's son Conall - who include Aed Sláne
That Aed Sláne was from Brega, and not from Tethbae, is also pretty clear
from his 'forainm' - 'Sláne', i.e. of Slane in the Boyne Valley.

I doubt it. There were three Aeds killed that year. The Annals of Tigernach
have Aed Sláne dying at Loch Semdige, Aed Buide (of Tethbae) dying at
Bruiden Da Choca, and Aed Rón of Uí Fhailgi dying on the green of mac Buain.
The source for some subsequent (understandable) confusion seems to be a
marginal gloss in the Annals of Ulster. This identifies the place of death
of one of the three Aed's as Loch Semdige. Charles-Edwards (very sensibly)
suspects that this gloss is intended to refer to Aed Sláne (Chronicle of
Ireland, vol i, p 123) even though it appears to be placed so as to refer
to Aed Buide instead. (Mac Niocaill, on the other hand, appears to read the
gloss as placed so as to refer to Aed Rón.)
