The history of the last name Iliff

The surname Iliff has its origins in England, with the earliest records dating back to the 12th century. It is believed to be derived from the Old English words "ile" meaning "district" or "region" and "yfre" meaning "boundary" or "border." This suggests that the name may have been given to someone who lived near a boundary or border area.

One of the earliest recorded instances of the name can be found in the Feet of Fines records for Essex in 1201, where a William Ilif is mentioned. The Feet of Fines were legal documents recording land transfers and property transactions. This indicates that the Iliff family had established roots in England by the late 12th or early 13th century.

In the 13th century, the surname appeared in various forms, such as Ilyff, Ilif, and Ilyfe, reflecting the variations in spelling and pronunciation common during that time. Several Iliff families were recorded in Sussex and Kent, suggesting that these counties may have been early strongholds for the name.

One notable figure from this period was John Iliff, a landowner and merchant from Kent, who was born around 1280 and is mentioned in the Patent Rolls of 1316. These rolls were official records issued by the English Crown and provide valuable insights into the lives and activities of prominent individuals.

During the 16th century, the surname Iliff began to spread across other parts of England, including Yorkshire and Lincolnshire. In the parish records of St. Mary's Church in Beverley, Yorkshire, there are entries for the baptisms of Thomas Iliff in 1592 and Elizabeth Iliff in 1597.

One of the most famous individuals with the Iliff surname was Robert Iliff, a renowned English poet and playwright born in London in 1610. His works, including the play "The Tragic Revolt" and the poetry collection "Sonnets of Melancholy," were widely acclaimed during his lifetime and contributed to the literary landscape of the 17th century.

In the 18th century, the Iliff family continued to thrive, with several members achieving notable positions in society. William Iliff (1720-1795), a wealthy merchant from Bristol, was a prominent figure in the city's trade and commerce. His son, James Iliff (1758-1832), followed in his footsteps and became a successful businessman and philanthropist, known for his support of various charitable causes.

As the centuries progressed, the Iliff surname spread further across the British Isles and eventually to other parts of the world through immigration and migration. While the name may have evolved in spelling and pronunciation over time, its origins can be traced back to the early days of English history, reflecting the rich tapestry of cultural and linguistic influences that have shaped the development of surnames.
