The McClintock family of Red Hall, Ballycarry, Co. Antrim are a descendant branch of the McClintock family of Drumcar, Co. Louth, later Lords Rathdonnell. This branch of the family can be traced from the diarist, Henry McClintock (fl. 1805-1843) who served as cornet in the 3rd Prince of Wales's Regiment of Dragoon Guards and subsequently as Port Surveyor of Customs in Dundalk. He was a younger son of minor landowner, John McClintock of Drumcar (1743-1799). Henry’s own son was the British arctic explorer Admiral Sir Francis Leopold McClintock (1819-1907). In 1870, Sir Francis married Annette Dunlop, daughter of R.F. Dunlop of Monasterboice House and Anna, Viscountess Massereene. Their son, Vice Admiral John William Leopold McClintock (1873-1947) also went on to distinguish himself in naval affairs taking a commanding role in World War One on HMS Lord Nelson at Gallipoli, 1915-16, and on HMS King George in the Grand Fleet from 1917-18. He was afterwards President of the Royal Navy College at Greenwich. He married the Hon. Rose Anne Mary O’Neill, second daughter of Rev. William Chichester (d. 1883), first Lord O’Neill. In 1927, he purchased the house of Red Hall where his son, John McClintock still resides.\n\nSource:\n<a href="http://www.lisnavagh.com/" target="new_window"> http://www.lisnavagh.com/</a>;\n\n<a href="http://www.ulsternet-ni.co.uk/larnwk49/LARPAGES/LNEWS2.htm" target="new_window">http://www.ulsternet-ni.co.uk/larnwk49/LARPAGES/LNEWS2.htm</a>.
