Stephen of Montfaucon
Stephen of Montfaucon (1325–1397), son of Henry I and Agnes of Montbéliard, was Count of Montbéliard from 1367. In 1354 he married Margaret of Chalon-Arlay and governed the county during his father's later campaigns.
His heir Henry II fell fighting the Ottomans at Nicopolis in 1396; Stephen sent men to search for him in vain. All his children died before him, and by his 1397 will he left Montbéliard to his ten-year-old granddaughter Henriette, betrothed to Eberhard IV of Württemberg, so carrying the county into the House of Württemberg.
