Irish Gods: Cessair

I got this from Wikipedia.

Cessair or Cesair (spelt Ceasair in modern Irish; anglicized Kesair) is a character from the Lebor Gabála Érenn, a medieval Christian pseudo-history of Ireland. According to the Lebor Gabála, she was the leader of the first inhabitants of Ireland, before the Biblical Flood.^[1] The tale may be an attempt to Christianize an earlier pagan myth,^[1] but may alternatively be the product of post-conversion pseudohistory.
