Etymology of the Name
Entries in the University of Wales' reconstructed Proto-Celtic lexicon (http://www.wales.ac.uk/documents/external/cawcs/pcl-moe.pdf ) suggest that the name is likely to be ultimately derived from the Proto-Celtic *Kridio-latoā, a phrase with the Proto-Celtic semantic connotations of ‘Female Heart-Felt Lust’ which aspect of nature She may well personify. If so, this would make her comparable to the Nordic Freja, Roman Venus, Greek Aphrodite, Canaanite Astarte, Assyrian Ishtar and Egyptian Hathor.
Creiddylad is a daughter of Lludd Llaw Eraint in Welsh mythology.
Interestingly, the names of Creiddylad's and Gwyn's fathers are cognates of the same figure.
Creiddylad's story is somewhat similar to Persephone's in Greek mythology, and the English version of her name is Cordelia, suggesting she may be related to the later character Queen Cordelia in Geoffrey of Monmouth's Historia Regum Britanniae and William Shakespeare's King Lear.
Creiddylad: Cymric goddess and heroine of the Mabinogi (Engenderer of Waters)
However, a short time before Creiddylad Ferch Lludd Llawereint (daughter of Lludd of the silver hand), who was loved by two men had bestowed herself upon Gwythyr fab Greidawl.
As a mother deity and a possible water goddess she might be similar to Dôn in embodying the creative spirit and being a 'mother of the tribe' type of divinity.
