Jeanne Filleaul-Brohy played one-ball and two-ball singles croquet at the 1900 Paris Olympics. Several of her relatives also competed in the 1900 croquet events, including her brother Marcel Haëntjens, and cousins Jacques Sautereau and Marie Ohier. Filleaul-Brohy came from a very well-to-do background, who lived a great bourgeois life of the “Belle Epoque” until World War I. She organized grand receptions in her castle, often attended by the world’s aristocracy, but she also farmed her land, raised cows, and made excellent butter. She was a fervent Catholic who devoted herself to religious and charitable works, and later entered the Franciscan lay orders as a Franciscan tertiary.
