Editing Cumhall (section)

== Battle and death ==

Tadg, slighted by Cumall's sweeping away his daughter, appealed to Cumall's lord, Conn of the Hundred Battles, and Conn gave choice of either relinquishing the daughter or suffer banishment. Cumall refused to give up his wife, and Conn made war against Cumhall, and Cumhall was killed by [[Goll mac Morna]] in this Battle of Cnucha,<ref name=hennessy-fotha-p88-91>{{harvp|Hennessy|1875|pp=88–91}}</ref> located at what is today [[Castleknock (barony)|Castleknock]].<ref>{{harvp|Meyer|1904}}, p. 180, note 3.</ref> Goll then took over leadership of the [[Fianna]], as explained in the ''Magnímartha Finn''.<ref>{{harvp|Meyer|1904}}, pp. 180–181 and verse: "'Tis for the chieftancy of Erin's fian / That they waged the stout battle".</ref>

Cumhall's wife Muirne was already pregnant with his son, Fionn, and Muirne's furious father Tadg not only refused to accept her back, but ordered her burnt to death.<ref>{{harvp|Hennessy|1875|pp=90–91}} and commentary, p. 87.</ref> Cumhall's wife however seeks Conn's protection, and in exile she delivers a child which she names Demni.<ref>{{harvp|Hennessy|1875|pp=90–91}}</ref>{{sfnp|Mackillop|1985|p=20}} Demni (Demne) later became Finn.<ref>{{harvp|Meyer|1904}}, p. 183: "Demne shall be named Finn (the Fair)".</ref>

Cumhall is reputed to be buried within the grounds of [[Castleknock College]], supposedly under a hill upon which an old water tower now stands.
