My pleasure. Hopefully the synergism of everyone working together will propel us farther and faster on our untangling efforts.
I have been down that rabbit hole myself:
The Ainnidh son of Duach you are wondering about is found on Bart's Table 7, Cenél Conaill as:(AFM555.2) “The battle of Cul Dreimhne was gained against Diarmaid, son of Cearbhall, by Fearghus and Domhnall, the two sons of Muircheartach, son of Earca; by Ainmire, son of Sedna; and by Ainnidh, son of Duach; and by Aedh, son of Eochaidh Tirmcharna.”

The quote from the Book Of Ballymote is indeed:
Which is roughly translated as:1601. Ocht mc. Ailella mc. Echach mugmedon, Ferghus Fiacra Ros otat Cenel Rosa Segna Cosmail Niall Eocho Liath Fidgenid.
The last two are my surmise as to the name split, Eóchád Grey (líath), and Fidgente a surmise taken from the Uí Fidgenti tribal name, assuming that Fidgenti is the genitive case of Fidgente. Reading through the article on the Uí Fidgenti, it does make one speculate if they may have descended from the Uí Ailella, since there seems to be no real consensus as to their origin.1601. Eight sons of Ailill son of Eóchád Muigmedón: (1) Fergus, (2) Fiachróe, (3) Ross, founder of the Cenél Rossa, (4) Ségán/Senán/Sétna (?, and I would guess Sétna as a "g" is easily confused from a "t" in Irish script), (5) Conmáel (?, as an "s" is easily confused from a "n" in Irish script, and there is the ever present incorrect case usage - nominative case máel vs. genitive case maíl), (6) Niall, (7) Eóchád Líath, and (8) Fidgente (?).
Also, the article says, “Closely related to the Uí Fidgenti were the Uí Liatháin”, so that is a possible connection to Eóchád Líath. Finally, the Uí Fidgenti progenitor is purportedly Fiachu Fidgenti, so there is a link to the Fiachróe name. There are definitely some Uí Fidgenti surnames that need to be investigated. As it stands now, the Y-DNA data indicates that the Uí Ailella should be in their own direct subbranch(es) of R1b-DF105.
Finally, if the Uí Crimthainn are R1b-FGC5939+ as we are currently speculating, AND R1b-FGC5939 is Uí Briúin Seóla as surmised, the Uí Briúin Seóla considered themselves to be the true line of Uí Briúin kings as descendants of Dau Tengae Umae, and the Uí Briúin Aí, Síl Muiredaig Ó Conchobair to be pretenders. Thus, the constant fighting between the Uí Briúin Seóla and Uí Briúin Aí. This could explain that fighting between the Uí Crimthainn and the Síl Muiredaig Ó Conchobair that kicked off ~1030 AD. The Uí Crimthainn may have decided they had gained enough power to challenge the Síl Muiredaig Ó Conchobair; although if so, as it turned out they were quite mistaken.
