Brother Solomon (Guillaume Nicolas Louis Leclercq) was born in Boulogne-sur-Mer (in the Diocese of Arras) on the 14th of November 1745. His father was a merchant operating in the port area of the town. He had 4 brothers.
In contrast to his four brothers, Nicolas attended the local commercial school run by the Brothers. This fact, combined with the Christian upbringing in his family, prepared the ground for his future vocation.
His father’s idea was to prepare his son to succeed him in the business. Indeed, as soon as Nicolas finished school he was employed by a merchant in the vicinity of Boulogne.
However, Nicolas did not want to pursue on being a merchant told his father about his dissatisfaction and his desire to follow the example of his school teachers.
He entered the novitiate in Saint-Yon, Rouen, on March 25, 1767, made vows in 1769 and was sent to teach in Maréville in September 1770. He made Perpetual Profession in 1772.
After having completed the 15 years of final profession required by Rule, he took part in the General Chapter of 1787. He was appointed as Secretary to the Chapter and after the Chapter he was asked to fulfill the same role in relation to the Superior General.
