Saint Geremarus (or Germer, Geremar, Geremaro; died 658) was a Frankish monk and abbot.His feast day is 24 September.
The oldest surviving biography of Saint Geremarus was composed in the 9th century, and was revised three centuries later, so its historical accuracy is very dubious.It is said that he was born in Vardes, Neuf-Marché, west of Beauvais, France, and was educated at the Episcopal School in Beauvais.He held high positions in the courts of the Merovingian kings Dagobert I (r. 629–639) and Clovis II (r. 639–657).He had two daughters and a son who died in infancy.
Geremarus met Audoin at Dagobert's court, and on his advice founded the Isle-sur-Epte Abbey (now Saint-Pierre-Bois).Audoin later ordained him as a priest.About 649 he moved to the, where he became the superior, but left after a revolt against his leadership.Again on Audoin's advice he founded a new monastery in Fly, now Saint-Germer-de-Fly Abbey.He died about three years afterwards.
