“ In 1769, after his father’s death, he went to Paris to be trained for the priesthood. On taking orders he assumed the additional surname of de Firmont, from the family estate of Firmount near Edgeworthstown.

In 1791 he became confessor to the princess Elizabeth, sister of Louis XVI., and earned the respect even of the sans-culottes by his courage and devotion. ”
