The aged Archbishop at once ratified the selection of the community, and warmly blessed the two candidates for the Mission, or, as he called them, the two foundation stones of the temple about to be erected in the New World for the glory of God. He prayed that the monastery at Quebec might be a home of grace, peace and benediction; that the efforts of hell might never prevail against it; and that the Lord might dwell there as the Father and Spouse not only of these its first inmates, but of all who should join or succeed them to the end of ages. He then appointed the Mother of the Incarnation Superior.
When all the preliminaries seemed satisfactorily concluded, it was found that an intimate friend of Madame de la Peltrie's had, at the last moment, revoked a promise to accompany her, alarmed, it would seem, at the perils of the voyage and the anticipated hardships of life in Canada. The circumstance was embarrassing, as little time now remained to seek a substitute, but the difficulty was removed in a manner as satisfactory as it was unexpected. There was just then in Tours a young person of respectable position and great piety, who, for the previous six years, had been determined on consecrating herself to the service of God and her neighbour in religion, but had deferred the execution of her design, merely because uncertainty as to the particular Order she was destined for. By the arrangement of Providence, her confessor, a Jesuit, happened likewise to be at Tours precisely at the moment of the nuns' perplexity, and, hearing of it, he suggested to them that the lady in question would very probably answer their purpose. She was at once presented to the missioners, and, on being asked by Madame de la Peltrie, whether she would consent to go to Canada as her personal companion, she promptly replied that her intention had been to become a nun, but that, since the Almighty was pleased to offer her so glorious an opportunity of sacrificing her life for Him, she would accept it with joy and gratitude. Her family name of Charlotte Barre she exchanged later for that of Mother St. Ignatius, under which we know her as the first sister professed at the Ursuline Convent of Quebec.
