Cilly is one of the many new names that came to England following the Norman Conquest of 1066. The Cilly family lived in Devon. Ancient records reveal the name Cilly is derived from the Old English word saelig, meaning one who is happy and blessed.

Early Origins of the Cilly family

The surname Cilly 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." 1 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." 2

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.

Cilly Spelling Variations

Anglo-Norman names tend to be marked by an enormous number of spelling variations. This is largely due to the fact that Old and Middle English lacked any spelling rules when Norman French was introduced in the 11th century. The languages of the English courts at that time were French and Latin. These various languages mixed quite freely in the evolving social milieu. The final element of this mix is that medieval scribes spelled words according to their sounds rather than any definite rules, so a name was often spelled in as many different ways as the number of documents it appeared in. The name was spelled Silley, Silly, Cele, Sully, Silliman and others.

Early Notables of the Cilly family

Outstanding amongst the family at this time was Sir John Sully (born c.1283-c.1388), of Ruxford and Iddesleigh in Devonshire, an English knight. The family were traditional lords of the manor of Iddesleigh in Devonshire. He was noted for giving evidence in Scrope v Grosvenor, one of the earliest heraldic law cases brought in England.

Migration of the Cilly family

Because of the political and religious discontent in England, families began to migrate abroad in enormous numbers. Faced with persecution and starvation at home, the open frontiers and generally less oppressive social environment of the New World seemed tantalizing indeed to many English people. The trip was difficult, and not all made it unscathed, but many of those who did get to Canada and the United States made important contributions to the young nations in which they settled. Some of the first North American settlers with Cilly name or one of its variants: Edward Silley settled in Virginia in 1635; Sarah Silley settled in Maryland in 1737; Hugh and John Silly settled in Barbados in 1660; Thomas Silly landed in Philadelphia, Pennsylvania in 1877.
