Reginald of Burgundy

Reginald of Burgundy (c. 1260–1321), a son of Hugh of Chalon and Countess Adelaide I, married Guillemette de Neufchâtel in 1282 and ruled Montbéliard and Belfort as count by right of his wife, heiress to both counties. In 1318, when Duke Eudes IV acquired the County of Burgundy by marriage, Reginald became its lieutenant-general.

He died in 1321. His son Othenin succeeded as Count of Montbéliard under his uncle's guardianship; after Othenin's death in 1339, the county passed to Reginald's daughter Agnes and her husband Henry of Montfaucon.
