Devastated by this refusal, Louise was at a loss as to her next step. When she was 22, her family convinced her that marriage was the best alternative. Her uncle arranged for her to marry Antoine Le Gras, secretary to Queen Marie. Antoine was an ambitious young man who seemed destined for great accomplishments. Louise and Antoine were wed in the fashionable Church of St. Gervaise on February 5, 1613. In October, the couple had their only child, Michel. Louise grew to love Antoine and was an attentive mother to their son. Along with being devoted to her family, Louise was also active in ministry in her parish. She had a leading role in the Ladies of Charity, an organization of wealthy women dedicated to assisting those suffering from poverty and disease.
