The Clan from whom the Gleish family descends began among the ancient Dalriadan kingdom of the west coast of Scotland. Their name comes from a devotion to Christianity. The Gaelic form of the name is M'A'Lios, which is a shortened form of Mac Giolla Iosa, meaning on of the servant of Jesus. 1 Cleish Castle is a 16th-century tower house in Kinross-shire, Scotland, west of the hamlet of Cleish.

Migration of the Gleish family

Significant portions of the populations of both the United States and Canada are still made up of the ancestors of Dalriadan families. Some of those in Canada originally settled the United States, but went north as United Empire Loyalists in the American War of Independence. The late 19th and early 20th centuries saw the ancestors of many Scots on both sides of the border begin to recover their collective national heritage through Clan societies and highland games. Some of the first North American settlers carried this name or one of its variants: Anne McLeish settled in Pennsylvania in 1833; George and Catherine McGillis settled in Pennsylvania in 1773.
