Léo Aucoin was born May 27, 1923 in Saint-Joseph-du-Moine, the fourth of twelve children born to Pat (à Jos à Dosithe à Michouque à Grannoume) Aucoin and Minnie (à Minou à Janvier à Frédérick à Augustin) Deveau.
When he was still quite young, Léo started singing old traditional songs without accompaniment. Over the years he became well known in the art of singing to the rhythms of his foot tapping. He collected and memorized many old Acadian songs. During his life, he learned hundreds of traditional songs and transcribed them in notebooks.
Léo Aucoin sang traditional Acadian songs at Expo ’86 in Vancouver, British Columbia. He also performed at a special concert “Symphonie au Coeur de l’Acadie” in 1993, marking the centenary of Église Saint-Pierre in Chéticamp. Léo Aucoin also sang in the Helen Creighton Folk Festival in Dartmouth in 1992.
In 2001, Léo recorded more than 150 Acadian songs at Studio Marcel Doucet in Chéticamp. This special project was funded by Heritage Canada, l’Université Sainte-Anne and Nova Scotia Department of Tourism, Culture and Heritage.
Léo Aucoin recorded his own compilation CD of 21 traditional Acadian songs in 2002.
