Harvey IV, Lord of Léon
Harvey IV of Léon was the eldest son of Harvey III of Léon and his wife, Margaret of Châteauneuf.Life
After his father’s death in 1240, Harvey, who was still a minor, became Lord of Léon. His fief was the castle of La Roche-Maurice.
Harvey IV was still a minor when his father died and the Lordship of Léon was ruled but the Duke of Brittany, John I the Red. Harvey seems to have lived in France, where he married Maud of Poissy, daughter and heiress of William of Poissy and his wife Isabella of Marly, and used the title Lord of Châteauneuf, which he had inherited from his mother Margaret of Châteauneuf, until 1260. At this date, Harvey acknowledged John I’s authority and paid him homage.
In September 1281, he gave all his properties in Châteauneuf and Senonches to King Philip III the Bold. This part of Harvey’s inheritance then passed to Louis of Valois, Count of Chartres and Alençon, who was granted Châteauneuf-en-Thymerais. Louis died without issue in 1328/29 and King Philip VI gave a part of Louis’ inheritance to his younger son Charles II of Valois, Count of Alençon and Perche, granting him Châteauneuf-en-Thimerais and Senonches, as well as Champrond, among other lands, in a charter dated May 1335.
Harvey died c. 1290 and was buried in the Abbaye Notre-Dame de Fontaine-Guérard.Issue
