Milo II was able to pass on the county undivided to his eldest son, Guy, in 1125 after his second son, Raynaud, entered the church and his third son, Herbert, married the heiress of the lordship of Ville-sur-Arce. Guy likewise passed on an undiminished county to his eldest son, Milo III. He died in 1151 only a year after his marriage to Agnes, heiress of Braine and Baudement. His heir was their only child, the infant Petronilla. Her uncle, Manasses, a cleric, ruled the county in her name until her marriage to Hugh of Le Puiset in 1168. Hugh ruled the county for the next twenty-one years, first in the name of his wife and from 1174 in the name of their son, Milo IV.
