MORRISSEY Family History

This interesting surname has two distinct possible sources. Firstly, the surname may be of Irish origin, and is an Anglicized form of the Gaelic "O'Muirgheasa", descendant of "Muirgheasa", a personal name apparently derived from the elements "muir", sea, and "geas", action, and are a branch of the "Ui Fiachra", having their territory at the southern side of Sligo Bay. These are of MacDermot stock, being descended from Muiris, the grandson of a famous MacDermot. However, there is no Gaelic sept of Morrissey associated with Munster or Leinster.

My great x 3 paternal grand mother was Ellen Morrissey, born in County Kerry, 1841. Her mother was Honora Sullivan, I am unsure of her fathers name. Ellen married James Thomas Keane (B. 1837 County Kerry D. 1918 Temuka, New Zealand) and they immigrated to New Zealand, settling in Temuka. Ellen died in 1878. I have been unable to find anymore information beyond this and would love to make family connections also. Please contact Debi if you can help or may be family-
