Condla's tale is given in the Echtra Condla. It is a rather fanciful tale of seduction by a fairy woman and leaving Ireland, never to return; and thus leaving his brother Art alone, the only surviving son of Conn. This is the meaning of Art's sobriquet Óenfer: one man or solitary. Although it may have been embellished with fanciful elements, it does provide an explanation for a son who went on some foreign adventure and never returned but who did leave offspring; whether in Ireland or elsewhere is unclear as yet.117.

It would also appear that he was possibly conflated with Condla Cáem. As noted many times, conflation and confusion of people and place names seems to be the biggest bane of the Irish histories and genealogies. There are other possibilities, but given the early nature of the split between R1b-DF105 and R1b-FT14462, Condla offers the best option currently.
FYI, the Domnall branch shown below, IMO, is one that never existed; or possibly one that died out or that we have seen no test results from. This branch would almost certainly split the current R1b-DF105 phylogenetic node, which we have not seen at all. This is who some people say is the progenitor of the Uí Maini of Connacht; but the Y-DNA does not support this in any way, while it does support the genealogy of the original Connachta very well with the splits under R1b-DF105. Bear in mind that Eóchád Muigmedón is assigned FAR more grandsons than there are direct subclades of R1b-DF105; so even if some of these grandsons are specious, there are still plenty to account for all of the direct subclades.
