- At the time of Griffith's Valuation Edward Donatus O'Brien held an estate in the parishes of Kilmurry, barony of Ibrickan, and Rath, barony of Inchiquin, county Clare and his mother, Jemima, held over a 1000 acres at Fanore More in the parish of Killonaghan, barony of Burren. He was descended from Henry O'Brien of Stonehall and his wife, Susannah Stafford. His father, Donatus O'Brien of Fanore, died in 1842. The family appear to have been resident at Sidmouth in Devon by the mid 19th century. In February 1857 the Scrappul estate, amounting to almost 4,000 acres, in the barony of Ibrickan belonging to O'Brien family members was advertised for sale, along with some land in the barony of Inchiquin and 687 acres in the barony of Owney and Arra, county Tipperary. Matthias Kenny appears to have bought the Scrappul estate. The lands in Inchiquin were purchased by Mr. Lahiff and in trust by Mr. Clay. In November 1858 the lands of Fanore were advertised for sale. Edward Donatus O'Brien was living in Llangollen, Wales, when he died in 1865.
