Thanks Michael Leydon for your reply and also to hallmark for the links.
My 2nd Great Grandmother was Alice Hooks who I believe at this stage was born in Ardtarmon. Possibly her sisters were Maria and Catherina and her parents were either Jacob or Joannes Hooks and Maria Moran or Kilmartin. I can't be certain about these though.
What I can be certain is, is that Alice (or Alicia) married Michael O'Hara and had four children, Maria, (1864-1901 who was my great grandmother and moved to Leeds when she was around 17 as that was when she married a man who was 31 with a son, - her marriage cert stated her father was deceased) Bridget, John and Michael, all living at Rathcormac at the time of their births, ( their christenings being in Roman Catholic Drumcliffe Magherow - sponsors were Martinus Hooks and Margareta McGonigle). What happened to Maria's siblings is unknown....I can't find anything about them at this stage.
I have no further roots in Ireland for this side of the family so I am at a dead end.
Any further information regarding the Hook's from that area would be much appreciated.
Thanks again for your interest.
