"Noble as a Montmorency" says a well-known adage. The founder of that illustrious line, Bouchard, Lord of Montmorency, figures as early as 950 A.D. among the great vassals of the kingdom of France. The heads of this house bore formerly the titles of First Christian Barons and of First Barons of France; it became allied to several royal houses, and gave to the elder daughter of the Church several cardinals, six constables, twelve marshals, four admirals, and a great number of distinguished generals and statesmen. Sprung from this family, whose origin is lost in the night of time, François de Laval-Montmorency was born at Montigny-sur-Avre, in the department of Eure-et-Loir, on April 30th, 1623. This charming village, which still exists, was part of the important diocese of Chartres. Through his father, Hugues de Laval, Seigneur of Montigny, Montbeaudry, Alaincourt and Revercourt, the future Bishop of Quebec traced his descent from Count Guy de Laval, younger son of the constable Mathieu de Montmorency, and through his mother, Michelle de Péricard, he belonged to a family of hereditary officers of the Crown, which was well-known in Normandy, and gave to the Church a goodly number of prelates.
Like St. Louis, one of the protectors of his ancestors, the young François was indebted to his mother for lessons and examples of piety and of charity which he never forgot. Virtue, moreover, was as natural to the Lavals as bravery on the field of battle, and whether it were in the retinue of Clovis, when the First Barons received the regenerating water of baptism, or on the immortal plain of Bouvines; whether it were by the side of Blanche of Castile, attacked by the rebellious nobles, or in the terrible holocaust of Crécy; whether it were in the _fight of the giants_ at Marignan, or after Pavia during the captivity of the _roi-gentilhomme_; everywhere where country and religion appealed to their defenders one was sure of hearing shouted in the foremost ranks the motto of the Montmorencys: _"Dieu ayde au premier baron chrétien!"_
Young Laval received at the baptismal font the name of the heroic missionary to the Indies, François-Xavier. To this saint and to the founder of the Franciscans, François d'Assise, he devoted throughout his life an ardent worship. Of his youth we hardly know anything except the misfortunes which happened to his family. He was only fourteen years old when, in 1636, he suffered the loss of his father, and one of his near kinsmen, Henri de Montmorency, grand marshal of France, and governor of Languedoc, beheaded by the order of Richelieu. The bravery displayed by this valiant warrior in battle unfortunately did not redeem the fault which he had committed in rebelling against the established power, against his lawful master, Louis XIII, and in neglecting thus the traditions handed down to him by his family through more than seven centuries of glory.
