Bitric did not keep his lands for long. They soon passed to one of King William’s followers, Edward of Salisbury, the Sheriff of Wiltshire, and then to Humphrey de Bohun when he married Edward’s daughter, Maud.
de Bohun established the Barony of Trowbridge and built a Motte and Bailey castle in order to consolidate his powerbase, and when Civil War erupted in England in 1139, the de Bohun family supported Empress Matilda in her claim against King Stephen.
The de Bohun family grew in wealth and influence and by the early thirteenth Henry (now the Earl of Hereford) was granted the right to hold a market and fair from King John in 1200, one of the first such charters recorded in the country, and he rebuilt the parish church. Unfortunately, Henry fell out with the King John and became one of the 25 rebel barons who forced him to accept the terms of Magna Carta in 1215.
