A daughter of Marie-Nicole Coutier and her first husband, Louis Laval, married a few years later the painter from Reims Nicolas Perseval .

Jacques Wilbault painted mainly portraits, and religious themes. These works on religious themes have been present in many churches and buildings in Porcien and Rethélois . Some are still present there, as well as at the Saint-Etienne cathedral in Châlons-en-Champagne . But many paintings disappeared during the French Revolution . Interrupted for a moment, this religious production was able to resume under the First Empire .
