He was called Ardgar mac Lochlainn, so his father was Lochlainn, but which
one is a matter of disagreement in the genealogies. NHI shows two
possibilities, Lochlainn m. Mael-Sechnaill (RIN 9304*) and Lochlainn m.
Muiredaig (RIN 7782*).
"Seamus O'Ceallaigh, _Gleanings from Ulster History_, 1951, shows that the
pedigree deriving from Ardgal MacLochlainn, ancestor of the MacLochlainn kings
of Ireland, from Muircertach, son of Niall Glundub (as found, for example, in
Turton's _The Plantagenet Ancestry_ 86) is less likely that an alternate
pedigree deriving him from Domnall, brother of Niall Glundub." [This quoted
from Kelley's "Descent from the Kings of Strathclyde".] So I have chosen to
show the more likely Lochlann according to this.
