Her husband, made peer of France with the title of Marquis de Cinq-Cygne, became lieutenant-general in 1816, and was rewarded with the blue ribbon for the eminent services which he then performed.
Michu's son, of whom Laurence took care as though he were her own child, was admitted to the bar in 1817.

After practising two years he was made assistant-judge at the court of Alencon, and from there he became _procureur-du-roi_ at Arcis in 1827.

Laurence, who had also taken charge of Michu's property, made over to the young man on the day of his majority an investment in the public Funds which yielded him an income of twelve thousand francs a year.

Later, she arranged a marriage for him with Mademoiselle Girel, an heiress at Troyes.
The Marquis de Cinq-Cygne died in 1829, in the arms of his wife, surrounded by his father and mother, and his children who adored him.
At the time of his death no one had ever fathomed the mystery of the senator's abduction.
