I believe that that Michael Fallon's mother Maria was Maria Egan, daughter of Thomas Egan (abt 1828 - 1904) and Margaret Creed (abt 1831 - 1903) of Cloonfad, Termonbarry, Roscommon.
My great grandfather Patrick Egan was Maria's brother. He was born in Cloonfad in about 1853 and died in Mareeba, Queensland, Australia in 1929.
Other siblings in the family that I am aware of are:
James Egan (1856 - 1921) who married Brigid Duffy and lived in Cloonfad.
Margaret (Maggie) Egan (1861 - 1931) who married John Noonan and lived in Knappogue/Cloondara, Longford.
William Egan (1873 - 1963) who married Mary Doherty (Michael Fallon was a witness at their wedding) and later Sarah Henegan. William lived in Rooskey.
