Looking for any information on my GGgrandmother she was a Dermody her name was Maria c1832 and her father was Kerin or Kyrn or Kyran c1810 and sister was Anastasia c1835 they came from Kilkenny Ireland but not 100% sure, Maria married Patrick Reidy from Limerick and he was a Policeman in Belfast(and survived) before they came to Australia in 1864. Anastatia married William Dwyer and emigrated to Australia in 1856. Also her mothers name was Margaret ??????? but she is shown to be in America after her husband(Kyran) died this was shown on Marias Immagration details in Australia.

Any ifo would be appreiated on how I can find their past in Ireland.
