Reilley

The name Reilley is an anglicized form of the Irish Gaelic name Reilly, which is derived from the Old Irish word "riaghail" meaning "rule" or "regulator." It is believed to have originated as a descriptive name or occupational surname for someone who worked as a steward or overseer.

The earliest recorded use of the name Reilley can be traced back to the 12th century in Ireland, where it was primarily found in the counties of Cavan, Longford, and Westmeath. In these regions, the Reillys were a prominent clan and held significant power and influence during the Middle Ages.

One of the earliest notable figures with the name Reilley was Maolmordha Reilly, who was the Chief of Muintir Reilly and lived in the 14th century. He played a crucial role in the ongoing conflicts between the Irish clans and the Anglo-Norman settlers in Ireland during that time.

Another prominent individual with the name Reilley was Edmund Reilly (1589-1669), an Irish Jesuit priest and author who spent much of his life in exile due to the persecution of Catholics in Ireland. He wrote several influential works on theology and philosophy during his lifetime.

In the 18th century, Andrew Reilly (1742-1809) was a notable Irish-American merchant and patriot who supported the American Revolution. He served as a member of the Pennsylvania General Assembly and was instrumental in the establishment of several educational institutions in Philadelphia.

Moving into the 19th century, John Reilly (1810-1888) was an Irish-American businessman and philanthropist who became one of the wealthiest men in New York City. He made his fortune in the textile industry and donated generously to various Catholic charities and educational institutions.

Another notable figure with the name Reilley was Albert Reilley (1883-1962), an American chemist and engineer who made significant contributions to the field of chemical engineering. He is best known for developing the Reilley Distillation Method, a widely used technique in the chemical industry.

While the name Reilley has Irish roots, it has since spread to various parts of the world, including the United States, Canada, Australia, and New Zealand, carried by immigrants from Ireland and their descendants.
