The Morrígan also appears in texts of the [[Mythological Cycle]]. In 12th-century pseudohistorical compilation the ''[[Lebor Gabála Érenn]]'' ("''The Book of the Taking of Ireland''"), she is listed among the [[Tuatha Dé Danann]] as one of the daughters of [[Ernmas]], granddaughter of [[Nuada]].<ref name="LGE-62,64"/>
The first three daughters of Ernmas are given as [[Ériu]], [[Banba]], and [[Fódla]]. Their names are synonyms for "Ireland", and they were respectively married to [[Mac Gréine]], [[Mac Cuill]], and [[Mac Cecht|Mac Cécht]], the last three Tuatha Dé Danann kings of Ireland. Associated with the land and kingship, they probably represent a [[triple deity|triple goddess]] of sovereignty. Next come Ernmas' other three daughters: [[Badb]], [[Macha]], and the Morrígan. A quatrain describes the three as wealthy, "springs of craftiness", and "sources of bitter fighting". The Morrígu's name is also said to be Anand.<ref name="LGE-62,64"/> According to [[Geoffrey Keating]]'s 17th-century ''History of Ireland'', Ériu, Banba, and Fódla worshipped Badb, Macha, and the Morrígan respectively.<ref>{{cite book |first=Geoffrey |last=Keating |title=The History of Ireland |url=http://www.ucc.ie/celt/published/T100054/text021.html |chapter=Book 2 Section 11}}</ref>
