François-Saturnin Lascaris d'Urfé, S.S. (1641 – June 30, 1701), was a French Sulpician priest known as the first resident pastor of the Parish of Saint-Louis du Haut de l'Île in what became the town of Baie-D'Urfé on the Island of Montreal in New France.
He spent some time directing the Sulpician mission, founded in 1676, at Mount Royal.
With the help of John Bernard Fitzpatrick, the founder of the College of the Holy Cross, James entered a Sulpician seminary in Montreal.
On 1 March 1824, in the company of Rev. Simon Gabriel Bruté, one of the professors of the seminary, afterwards first Bishop of Vincennes, he sailed for Europe to complete his studies in the Sulpician Seminaries of Issy and Paris.
Later, as an anti-Bonaparte activist, he was imprisoned in the fortress of Bellegarde, then released about 1805 and allowed to come to the United States, settling in Baltimore, Maryland, where he became an instructor in art and architecture at St. Mary's College, the Sulpician Seminary.
Ambrose Maréchal, the future third archbishop of Baltimore, and other Sulpician priests are frequent guests at Doughoregan, saying Mass there often and gaining the ear of the Signer.
