Lived 1764 – 1828 (aged 63). Ambrose Maréchal was a French catholic priest and catholic bishop.
Ambrose Maréchal, P.S.S. (August 28, 1764 – January 29, 1828) was a French-born Catholic prelate who served as archbishop of Baltimore from 1817 until his death. He was a member of the Sulpicians.
Maréchal dedicated the Cathedral of the Assumption of the Blessed Virgin Mary, the oldest cathedral in the United States, in Baltimore in 1821.

He also clashed with the new Bishops of Richmond and Charleston.
Biography
Early life Ambrose Maréchal was born at Ingré in France on August 28, 1764. Following his parents' wishes, he began studies for the legal profession. However, he later decided to enter the Saint-Sulpice Seminary at Issy-les-Moulineaux, France, with the intentions of becoming a priest. The Sulpician Order gave Maréchal his tonsure, a crown-like haircut allowing a seminarian to continue his studies, at the end of 1787.
Priesthood Due to popular unrest in the Paris area, Maréchal left the Saint-Sulpice Seminary for Bordeaux, France, in early 1792. Eleven Sulpician priests were murdered in France during this period. Maréchal was ordained there into the priesthood on March 25, 1792, by Archbishop Jérôme-Marie Champion de Cicé.
Bishop John Carroll of the Diocese of Baltimore in 1791 had invited the Sulpicians to Baltimore, Maryland to establish St. Mary's Seminary, the first Catholic seminary in the new United States. The Sulpician Order in the spring of 1792 sent Maréchal to the United States to help staff St. Mary's. He arrived Baltimore on June 24, 1792, where he celebrated his first mass as a new priest. After spending time at the seminary, he was assigned by the Sulpicians to perform pastoral work in Bohemia, Maryland. By 1799, Maréchal was back in Baltimore, teaching theology at the seminary. In 1801, the Sulpicians sent Maréchal to teach philosophy at the new Georgetown College in Washington, D.C.
With the ascension of Napoleon Bonaparte as first consul of the new French Republic, it became safer for Catholic clergy to practice in France. In 1803, the Sulpicians ordered Maréchal to return home. He would spend the next nine years teaching at Sulpician schools in Saint-Flour, Lyon, Aix-en-Provence and Marseille. In appreciation of his service, Maréchal's students in Marseille presented him with a marble altar. Louis XVIII, who became the French monarch in 1814, later presented him with several paintings. The altar and the paintings went to the Basilica of the Assumption in Baltimore. However, he did not want the appointment and the Vatican allowed him to decline it. On July 24, 1817, Pius VII appointed him as titular bishop of Stauropolis and coadjutor archbishop of Baltimore to assist the ailing Archbishop Leonard Neale. However, Neale died before Maréchal could be consecrated. The latter problem, known as trusteeism, was most pronounced in parishes with a dominant number of Irish immigrants. These trustees were willing to accept a cleric, regardless of their incompetence or lack of qualifications, as long as they were Irish. At the same time, the Propaganda Fide in Rome was receiving reports from primarily Irish parishes in Virginia and South Carolina that were unhappy with French priests who were not fluent in English or ignorant of local customs.
In 1816, Neale had to deal with a schism in Charleston, South Carolina. He had placed St. Mary's, a primarily Irish parish in that city, under interdict because its trustees had refused to accept a French priest that Neale had appointed as pastor. After several appeals to the Vatican, Pius VII upheld Neale's ruling on July 6, 1817, soon after his death. Even after receiving the pope's ruling, the trustees defied Maréchal, petitioning the Vatican to form a new diocese in the Carolinas. However, when Maréchal appointed an Irish priest to the parish, the trustees submitted to Maréchal's authority.
Maréchal in 1818 became involved with a second schism in Norfolk, Virginia, involving a French pastor, Reverend James Lucas, in an Irish parish. Complaining of Lucas' difficulty in conducting mass in English, the board of trustees had finally locked him out of St. Mary's church there. Neale then put that parish under interdict. The trustees petitioned the Vatican to lift the interdict and install an Irish priest of their choosing, Reverend Thomas Cabry. The Propaganda Fide suggested that Maréchal appoint Cabry, but Maréchal refused. Cabry then went to Norfolk and assumed the duties of pastor, despite Maréchal's threats.
Concerned that the schisms in Charleston and Norfolk might spread, the Vatican on July 11, 1820, erected the dioceses of Richmond and Charleston, taking the Southeastern United States away from the Archdiocese of Baltimore. Maréchal was very unhappy with this action, complaining that the Vatican never consulted him on their creation. Pius VII ruled in Maréchal's favor, but the Jesuits refused to comply with his, contesting ownership of White Marsh for many more years.
A more significant outcome of Maréchal's trip to Rome was the pope's agreement to consult with the archbishop of Baltimore on the erection of new dioceses and the appointment of new bishops in the United States. In January 1821, Kelly took up residence in Norfolk which had a larger Catholic population than Richmond. Kelly was soon involved in disputes with Maréchal over their jurisdictions. After returning to Baltimore from a trip to Canada in 1826, Maréchal went to Mount Saint Mary's Seminary in Emmitsburg, Maryland on a visit. While at the seminary, he experience his first symptoms of chest dropsy (heart failure). Ambrose Maréchal died at age 63 on January 29, 1828, in Baltimore. His body is interred in the crypt of the Baltimore Basilica; his heart is in the Historical Seminary Chapel of the St. Mary's Spiritual Center & Historic Site in Baltimore, the original St Mary's Seminary campus.
