Sullo is one of the names that was brought to England in the wave of migration following the Norman Conquest of 1066. The Sullo family lived in Devon. Ancient records reveal the name Sullo is derived from the Old English word saelig, meaning one who is happy and blessed.

Early Origins of the Sullo family

The surname Sullo 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.

Sullo Spelling Variations

Before the advent of the printing press and the first dictionaries, the English language was not standardized. Sound was what guided spelling in the Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Spelling variations were common, even among the names of the most literate people. Known variations of the Sullo family name include Silley, Silly, Cele, Sully, Silliman and others.

Migration of the Sullo family

To escape the political and religious chaos of this era, thousands of English families began to migrate to the New World in search of land and freedom from religious and political persecution. The passage was expensive and the ships were dark, crowded, and unsafe; however, those who made the voyage safely were encountered opportunities that were not available to them in their homeland. Many of the families that reached the New World at this time went on to make important contributions to the emerging nations of the United States and Canada. Research into various historical records has revealed some of first members of the Sullo family to immigrate North America: 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.
