I do not know the date or place of death for Jeremiah ‘Darby’ O’Brien in Australia. When I find it, I am hoping to find his mother’s name which will provide clues to finding our ancestors in County Clare, Ireland. The transcript of his wife Letitia’s death certificate informs us that her husband Jeremiah/Darby was deceased at the time of her death in Sydney 1889. The informant was Letitia’s son-in-law J. Cavanagh who may not have known his father-in-law and either he or the transcriber of the death certificate has made an error with Jeremiah’s christian name, recording it as James. According to Killaloe Parish Marriage Records, Darby O’Brien, residing in Knockadereen married (widow) , Letitia Roach/Roche (widow Crotty residing in Parish of Abington) in 1833. Catholic Parish Registers for the Diocese of Killaloe (1655-1915) record the Baptism of their child Fanny on 1 June 1834. The family residence is noted as Knockadereen (one of the townlands in the Parish of Killaloe). The Baptism sponsors were Biddy O’Brien and John Scanlan both from Garraunboy/Garrenboy/Gerrenboy/Geranboy, County Clare. Perhaps Biddy (short for Bridget) is Jeremiah’s sister? Thanks to the helpful members of the County Clare Ireland Genealogy Facebook Group who suggested I look at the Tithe Applotment Books (Irish National Archives), I found a Darby O’Brien listed as a Knockadereen landholder in 1828 in partnership with Dennis McKeough. If this is our Darby, could his mother be related to the McKeoughs? It is likely that the eldest daughter Maria, was born of her mother Letitia’s previous marriage to William Crotty. Finding Jeremiah’s parents is proving to be very difficult. I have found death and marriage records for all of Jeremiah and Letitia O’Brien’s daughters in Australia (more information to be eventually added to this blog) and they have provided clues as to the occupation of Jeremiah O’Brien. His youngest daughter Anna Matilda O’Brien, seamstress (1842 -1915) married William Graham (signwriter) in Fitzroy Victoria in 1867. On the marriage certificate, her father Jeremiah O’Brien’s occupation is listed as Contractor.
