Really, folks...if Noah lived to be 950 years old, does it stand to reason that he would only have 3 children????
In Irish mythology, Cessair (or Ceasair) was the leader of the first inhabitants of Ireland before the BiblicalFlood, in what may be a Christianisation of a legend that pre-dates the conversion, but may alternatively be the product of post-conversion pseudohistory.
She was daughter of Noah's son Bith and his wife Birren. According to legend, when her father was denied a place in the ark by Noah, Cessair advised him to build an idol. This idol advised them that they could escape the Deluge in a ship. Cessair, along with three men, Bith, Fintan and Ladra, and fifty women, set off and sailed for more than seven years. They landed in Ireland at Dún na mBarc (Donemark, on Bantry Bay in County Cork), forty days before the Flood, in 2958 BC according to the Annals of the Four Masters, 2361 BC according to Seathrún Céitinn 's chronology.
