Welcome to Ireland Reaching Out!
I have asked a local volunteer to have a look at this
Searching for information on the family of Bridget Halloran, born about 1818-1820, probably in Ogannelloe Parish or somewhere in the vicinity of Scarriff, County Clare. Married Edward O'Brien in 1860 in Watertown, New York, USA. Died in 1903 in London, Ontario, Canada. Possible names for her parents are Andrew Halloran and Mary Hart.
I have better info for Bridget's younger brother, Martin Halloran, that may help to identify the family's roots in Clare. Martin served in the British Army from 1850-1870 with overseas service in East India and Canada. His discharge papers (attached) state that he was "born in the Parish of O'Gunnalow near the Town of Killaloo in the County of Clare". His age at the time of discharge places his birth in about November 1831.
In searching the on-line records maintained by the Clare County Library, I've been able to identify some possible Halloran connections, but can't seem to narrow down the list. Any and all assistance will be appreciated.
