The history of the last name Ogan

The surname Ogan has its origins in Ireland, dating back to the medieval period. It is believed to be a variant of the Gaelic name Ó Dochartaigh, which means "descendant of Dochartach." Dochartach was a personal name derived from the word "dochartach," meaning "hurtful" or "obstructive."

The Ogan surname was predominantly found in the counties of Donegal and Derry, where the Ó Dochartaigh clan held significant power and influence. The name's earliest recorded spelling was Ogane, which appeared in the Annals of the Four Masters, a chronicle of medieval Irish history, in the 14th century.

One of the earliest recorded individuals with the Ogan surname was Cormac Ogan, a notable Irish poet and historian who lived in the 15th century. He is known for his work "The Book of Ballymote," a collection of historical manuscripts and literary works.

In the 16th century, the Ogan family was mentioned in the Fiants of the Tudor Sovereigns, a series of administrative records from the Tudor period in Ireland. These records document the granting of lands and titles to various Irish families, including the Ogans.

During the 17th century, the Ogan name appeared in the Petty's Census of Ireland, a survey conducted in 1659 by Sir William Petty. This census provides valuable insight into the distribution and prevalence of Irish surnames during that time period.

Notable individuals with the Ogan surname include:

1. Eoghan Ogan (c. 1550 – c. 1610), an Irish chieftain and leader of the Ó Dochartaigh clan in Donegal.
2. Niall Ogan (c. 1620 – c. 1690), an Irish soldier who fought for the Catholic Confederacy during the Irish Confederate Wars.
3. Séamus Ogan (c. 1670 – c. 1740), a renowned Irish poet and storyteller from County Donegal.
4. Margaret Ogan (c. 1780 – c. 1860), a philanthropist and landowner from County Derry who funded the construction of several schools and churches in the region.
5. Michael Ogan (1835 – 1912), an Irish-American soldier who served in the Union Army during the American Civil War and received the Medal of Honor for his bravery.

While the Ogan surname has its roots in Ireland, it has since spread to other parts of the world, particularly through Irish emigration. However, its rich history and deep connections to the Gaelic culture and traditions of Ireland remain an integral part of its legacy.
