- Cecil Stacpoole Kenny records the history of the Kenny family and of some other related county Clare families in a volume now preserved in the National Library of Ireland. He writes that an Edmond/Edward Kenny was the first to settle in county Clare. Edmund Kenny was a tenant of the Earl of Thomond at Tiermanna, barony of Ibrickan. Edmund's grandson Matthias by his wife Mary Shannon had seven sons. From their second son David Kenny descended General Sir Thomas Kelly Kenny. Their eldest son Edmund of Carhue was an extensive landholder in the Dysert locality. Edmund's eldest son William Kenny of Cragleigh had a large family. His second son Hugh Kenny of Ballygreen married Helen Macnamara of Corbally co heiress of her brother Thomas and they were the parents of Thomas Hugh Kenny, a solicitor, of Moymore, Indiaville near Limerick and Georges St, Limerick. In 1877 Thomas Hugh Kenny married Louisa Dunne, who inherited the Stacpoole of Moymore estate through her mother Mary Louisa Stacpoole. They became known as Stacpoole Kenny and had three sons and three daughters. Louise wrote popular novels and biographies. Other branches of the Kenny family intermarried with the Martyns of Gregans Castle, O'Gormans, Lingards, Lysaghts, Macnamaras and Ryans.
Kenny/Kelly Kenny (Treanmanagh)
- David Kenny of Tiermanna, barony of Ibrickan, county Clare, married Mary O'Gorman and died in 1833. He had six sons and two daughters. Cecil Stacpoole Kenny writes that their eldest son Matthias acquired estates. Reid writes that he bought almost 4,000 acres in the barony of Ibrickan. The O'Brien estate of Scrappul in the barony of Ibrickan was advertised for sale in February 1857. It was close to Doolough Lake. Matthias Kenny married but had no children, so he left his estates to his nephew General Sir Thomas Kelly Kenny. Thomas Kelly Kenny was the fifth son of Matthias's sister Mary who married Mathew Kelly of Kilrush, son of John Kelly of Craggaknock and his wife Anne Butler of Doonbeg. In the 1870s Matthew Kelly of Kilrush owned 1,277 acres and Captain Thomas Kelly Kenny owned 5,736 acres in county Clare. By 1909 the General had agreed to sell over 5,000 acres to the Congested Districts' Board. The General died unmarried in 1914.

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.
