Geoffrey IV of Joinville

Geoffrey IV (died August 1190), called the Younger (French Geoffroy le Jeune), was the Lord of Joinville from 1188 until his death on the Third Crusade two years later.

[1] In 1189, Geoffrey, with the consent of his two eldest sons, granted his vineyard at Mussey to the abbey of Saint-Urbain in return for mass being said for his father every year on the anniversary of his death.

At the same time, he granted the tithes of Charmes-en-l'Angle, to which he had right, to establish a prebend at Saint-Laurent for saying annual masses for himself and Héluis and for two masters: Acelin, teacher of his son William, and a certain Constant.

[1] Later that year, Geoffrey settled a dispute between the men of Vaucouleurs, a castle town belonging to Joinville, and the abbey of Vaux en Ornois over a meadow.

[1] The various religious acts undertaken in 1188 and 1189 were made in preparation for the Third Crusade, which Count Henry II of Champagne had vowed to join.

The month of his death is supplied by a 14th-century epitaph written by his grandson, John of Joinville, for his father, Geoffrey III, who was buried in the abbey of Clairvaux.
