The last know record for Daniel O’Brien was in the 1826 Tithe Applotment Books of Kilmurry-Ibrickane Parish. Daniel was listed as having 6 acres of land in the townland of Killernan, Co. Clare. He and his brothers, Patrick, James, Michael and father, John all lived on about 50 acres of land. Ireland’s population was growing at a rapid rate and the potato was feeding the masses. Twenty years later and after the Famine, the farms were consolidated to make them more efficient and profitable for the landlord. In 1855, the Griffith’s Valuation of land for Killernan townland only listed the families of Honoria O’Brien and her brother-in-law Michael O’Brien having two distinct farms. The land had been cleared of the unwanted Irish tenant, many through emigration and others by death from starvation as this newspaper article describes.
Daniel O'Brien was on his way to the home of Thomas Howard of Ballyvaskin, Miltown Malbay on his return from the Work House in Ennistymon. Thomas Howard was married to Mary O'Brien of Killernan on Feb 16th 1846. Mary O'Brien Howard was probably a neice of Daniel O'Brien.
