One of the earliest recorded instances of the ILLY surname appears in a document from the 13th century, which mentions a man named Giovanni ILLY residing in the town of Cuneo, Piedmont. This suggests that the name had already become established in the region by that time.

In the 15th century, the ILLY name appeared in a manuscript detailing the noble families of the city of Turin, indicating that members of the family had achieved a certain level of prominence and social status.

A notable figure from the ILLY lineage was Francesco ILLY, a renowned artist and sculptor who lived in the late 16th and early 17th centuries. He was renowned for his intricate marble sculptures, many of which can still be found adorning churches and public buildings throughout northern Italy.

Another notable bearer of the ILLY surname was Giambattista ILLY, a prominent lawyer and jurist who lived in the 18th century. He served as a magistrate in the city of Asti and was known for his deep knowledge of Roman law and his fair and impartial rulings.

In the 19th century, the ILLY family continued to make their mark in various fields. Pietro ILLY (1810-1892) was a successful entrepreneur who established a thriving textile business in the city of Biella, while his contemporary, Giulia ILLY (1825-1898), was a celebrated philanthropist and patron of the arts.
