Sometime before 1141, possibly as early as 1135, Matilda married
Ranulf de Gernon, 4th Earl of Chester, and was accorded the title of Countess of Chester. Her husband had considerable autonomy in his
palatine earldom. In January 1141, Earl Ranulf and Countess Matilda were at
Lincoln Castle when it was besieged by the forces of King
Stephen of England. The following month, a relief army loyal to
Empress Matilda and led by her half-brother
Robert, Earl of Gloucester, who was also the father of Countess Matilda, defeated and captured King Stephen in the fierce fighting, later known as the
First Battle of Lincoln. In return for his help in repelling the king's troops, the Earl of Gloucester compelled the countess's husband to swear fealty to the Empress Matilda. On 29 August 1146, Earl Ranulf was seized by King Stephen at court in
Northampton. Stephen later granted him the castle and city of Lincoln sometime after 1151. ==Children==
