BIOGRAPHY Guillaume du Parc, seigneur d'Availlis, was the second son of Alain III, seigneur de la Motte-du-Parc, and Judith de Beaumanoir. About 1350 he married Guillemette de Romilly, dame de Cresnay near Avranches, her family named after the fief of Romilly which she held, member of an old, substantial house in Brittany and Normandy. They had two sons, Robert and Robin, both of whom married. Robin's son Bertrand by his wife Jeanne de Gaunay died without progeny, naming as his heir Jean du Parc, grandson of his uncle Robert.

Guillaume served under Bertrand Du Guesclin, le Connetable du Guesclin, in Guienne, Saintonge and Périgord. In 1382 he joined the unsuccessful campaign of Louis I, duc d'Anjou, to claim the throne of Naples, following the death of Queen Joanna I, his first cousin once removed. Guillaume returned to France about 1385, and in 1390 he joined the crusade launched by Louis II, duc de Bourbon, against the Hafsids of Tunis, in conjunction with the Genoese, to suppress piracy based in the city of Mahdia. In the unsuccessful siege of Mahdia he was severely wounded. In 1403 he purchased with his son Robert the estate of Bernières near Vire. He died about 1404.
