Léocadie Gascoin (March 1, 1818 – January 29, 1900) was the co-founder and superior of the Sisters Marianites of Holy Cross. Her name in the congregation was Marie des Sept-Douleurs.

Life Léocadie-Romaine Gascoin was born on March 1, 1818, in Montenay, France. She was the fourth of six children born to middle-class farmers Michel-Jean and Rosalie-Renée Chardon Gascoin. Her mother died in 1822. Leocadie attended the local parish school and spent most of her early life at home taking care of her family. From 1833 to 1837 she went to a boarding school in Laval. She joined Father Basile Moreau in 1841 to found the Marianite Sisters of Holy Cross at Le Mans.

She entered the novitiate in Le Mans and received her religious formation at the Monastery of the Good Shepherd in Le Mans under the direction Mother Mary of St. Dosithee.
