Benoît Grellet de la Deyte was seigneur of Saint-Quentin (in the Somme Department)and of Fayet-Ronaye.

Feudal remains (presumably, ruins of the family castle of Grellet de la Deyte) are situated between Frissonet, one of the hamlets of Fayet-Ronaye, and Saint-Germain-l'Herm.

According to the researcher Coste ("Supplément au monument druidique de Tuniac"),[4] a burial mound, known as the Dissard's tumulus, located 1 km south away from the center of the village, contained the rests of the druidic chef and his Celtic supporters chased by the army of Marcus Licinius Crassus.

[6] Situated between Fayet and Saint-Germain-l'Herm, the Cromlech of Frissonnet represents a square formed with megalithic standing stones.
