Cilley History, Family Crest & Coats of Arms
Cilley is one of the thousands of new names that the Norman Conquest brought to England in 1066. The Cilley family lived in Devon. Ancient records reveal the name Cilley is derived from the Old English word saelig, meaning one who is happy and blessed.
Early Origins of the Cilley family
The surname Cilley was first found in Devon where they were granted lands by William the Conqueror for their assistance at the Battle of Hastings in 1066 A.D. They were Lords of the manor of Rackenford, and were conjecturally descended from Jocelyn who held the lands at the time of the taking of the Domesday Book in 1086 A.D. from Baldwin, the Sheriff. The family may have originated in Cornwall as in "John Silly, gentleman of St. Wenn, altered his name from Ceely to Silly."  No dates were given with the previous quote. However, we did find another note about the family in the parish of Helland, Cornwall. "Another barton called Kernick, which was for some time the residence of a family called Silly, became the property of Sir John Morshead." 
One of the earliest records of the name was Henry de Sully (or Soilli) (died 1195), was a medieval monk, prior of Bermondsey Abbey in 1186, Bishop of Worcester (1193-1195) and Abbot of Glastonbury.
William, Count of Sully, also known as William the Simple (c. 1085-c. 1150) was Count of Blois and Count of Chartres from 1102 to 1107, and jure uxoris Count of Sully. William was the eldest son of Stephen-Henry, Count of Blois and Adela of Normandy, daughter of William the Conqueror. In 1104, William married Agnes of Sully, the heiress to the lordship of Sully-sur-Loire. Together they had six children including Henry de Sully (died 1189), the medieval Abbot of Fécamp and Bishop-designate of Salisbury and Archbishop-elect of York in 1140.
Over in France, Maurice de Sully (died 1196) was Bishop of Paris from 1160 until his death. He is best known for overseeing the building of Notre Dame Catherdaral.

Faced with the chaos present in England at that time, many English families looked towards the open frontiers of the New World with its opportunities to escape oppression and starvation.
