McClay

McClay is a Scottish surname. It is derived from Gaelic Mac an Léigh, or possibly a Highland adaption of the Irish Gaelic Mac Duinnshléibhe (anglicised Donlevy) where the Scots aspirated the “D” and then dropped the final “e” from the Irish language form of the name.[citation needed]

When the north-eastern Irish kingdom of Ulaid fell to John de Courcy in 1177, many of the MacDonlevy dynasty sought asylum in the Highlands of Scotland. Their MacDonlevy surname evolved there first to Maconlea, also, MacConloy, McCloy and, then, to MacALeavy, MacAlea, MacLea, MacLay, McClay and, even, Leevy, Levy (surname) and Leavy.[1][2][3] Some sources contend that the surname McClay, like the surname MacKinley, arises instead from a Gaelic language nickname given the MacDonlevy in both the Scottish Highlands and elsewhere. That nickname is Mac an Leigh, translating to English as leech, but meaning a physician. Leeching (medical) was in Gaelic Ireland, Scotland and elsewhere for millennium a pervasive medical therapy. The MacDonlevy were also one of Ireland’s ancient hereditary medical families.[4][5] Notable people with the surname include:

* Allen McClay (1932–January 2010), British businessman
* Andy McClay (born 1972), Scottish footballer
* Roger McClay (born 1945), New Zealand politician
* Ryan McClay (born 1981), American lacrosse player
* Todd McClay (born 1968), New Zealand politician
* Wilfred M. McClay, American historian
* Will McClay (born 1966), American footballer and coach

Note on list of Stuart loyalists massacred at the 1647 Battle of Dunaverty in Kintyre, Scotland, “Of the surnames appearing in the second column the M'onleas were originally M'Dunleas; the D disappears through euphonistic elision in Gaelic. Although Niall 10th Duke of Argyll, thought it quite possible that their eponymic ancestor was Dunsleve, the son of Aedh Alain, the O'Neill Prince evidence now leads to the conclusion that they are descendents of the Ruaidhri Mac Duinnsleibhe, the last king of Ulidia.”
