This family was associated with the Ennis locality in county Clare from the late 17th century. Daniel Finucane of Ennis and Carrowreagh, parish of Kilfiddane, barony of Clonderalaw, married Helen O’Shaughnessy from Gort, county Galway. Their grandson James Finucane was in possession of the lands of Ballynacraggy, parish of Kilnasoolagh, barony of Bunratty Lower, by the mid 18th century and his son John, a Dublin attorney, married in 1774 Elizabeth O’Brien, who brought with her a fortune of £21,000. Members of this family appear to have been mainly resident on the Continent. In 1800 James Finucane, son of John and Elizabeth married his cousin Jane Finucane of Lifford House, Ennis, and they had a large family, one son and nine daughters. One daughter, Louisa, was married in 1854 to Lucius 13th Baron Inchiquin. Their son Michael died without marrying and the estate appears to have been divided between some of his sisters. At the time of Griffith’s Valuation the representatives of Michael Finucane owned an estate mainly in the barony of Corcomroe, parishes of Clooney and Kilmanaheen. Their estate also included land in the parishes of Clondagad and Killone, barony of Islands and Kilnasoolagh, barony of Bunratty Lower. In the 1870s Michael's sisters Anastasia Finucane of Onslow Gardens, London, Fanny Woodward and Alicia de Haye of Versailles owned 1,972, 855 acres and 618 acres respectively in the county.
