Baron Maclay, of Glasgow in the County of Lanark,[1] is a title in the Peerage of the United Kingdom. It was created in 1922 for the Scottish businessman Sir Joseph Maclay, 1st Baronet. He was Chairman of Maclay & Macintyre, shipowners, of Glasgow, and also served as Minister of Shipping in the war-time coalition of David Lloyd George, without being in Parliament. Maclay had already been created a Baronet, of Park Terrace in the City of Glasgow in the County of Lanark, in 1914.[2] His eldest surviving son, the second Baron, represented Paisley in the House of Commons as a Liberal. As of 2010[update] the titles are held by the latter's eldest son, the third Baron, who succeeded in 1969.
In 1913, the first Lord Maclay purchased Duchal House in Kilmacolm, Inverclyde which remains the family home to this day. The former Lords Maclay are buried alongside the Viscount Muirshiel in the graveyard of Mount Zion Church in Quarrier's Village.
