The Scottish and Irish surname McDade is of patronymic origin being an anglicized form of the Gaelic surname Mac Daibheid, meaning “son of David.” The McDade’s are said to have descended from David O'Doherty, a chief of Cinel Conaill, who was killed in 1208, and grew to be numerous in Inishowen. The name is found most frequently around Glasgow, Scotland and Donegal and Derry in northern Ireland. The earliest recording of the name in the New World is in 1803 when Owen McDade, aged 28, arrived in Philadelphia. Today there are approximately 7,000 bearers of the name McDade in the United States. A notable bearer of the name was the Scottish poet and anti-fascist Alex McDade from Glasgow who died in Spain fighting with the International Brigade against Franco’s fascist forces.
