The history of the last name O'Guinn

The surname OGUINN has its origins in Ireland, with the first records of the name appearing in the late 16th century. It is believed to be derived from the Irish Gaelic name "Ó Goinn," which means "descendant of Conn." Conn was a popular given name in medieval Ireland, and it is thought that the name may have originally referred to someone who was a descendant of a person named Conn.

One of the earliest recorded instances of the name OGUINN can be found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the 17th century. The Annals mention a certain Godfrey OGUINN, who was a prominent figure in County Monaghan in the late 16th century.

In the 17th and 18th centuries, the name OGUINN was particularly concentrated in the counties of Monaghan and Cavan, which were strongholds of the clan. During this period, the name was also sometimes spelled as "O'Guinn" or "Oguin."

One notable figure with the surname OGUINN was Patrick OGUINN (1670-1744), who was a prominent landowner and member of the Irish Parliament in the early 18th century. He represented County Monaghan in the Irish House of Commons from 1703 to 1714.

Another individual of note was Terence OGUINN (1725-1802), a Catholic priest and scholar who was born in County Cavan. He was known for his efforts to promote education and literacy among the Irish Catholic population at a time when such activities were heavily restricted by the Penal Laws.

In the 19th century, the surname OGUINN began to spread more widely across Ireland and beyond, as many families emigrated to other parts of the world, particularly the United States and Canada. One notable American with the surname was Michael OGUINN (1842-1912), who served as a Union soldier during the American Civil War and later became a successful businessman in Chicago.

Another prominent figure was Mary OGUINN (1870-1954), who was born in County Monaghan but later moved to the United States. She was a prominent educator and advocate for women's rights, and was involved in various social and political movements in New York City in the early 20th century.

Overall, the surname OGUINN has a rich history that can be traced back to medieval Ireland and the descendants of a man named Conn. While the name was once concentrated in specific regions of Ireland, it has since spread around the world, carried by families who have made their mark in various fields over the centuries.
