The history of the last name Dermott

The surname DERMOTT originated in Ireland and can be traced back to the 12th century. It is an Anglicized version of the Irish Gaelic name O'Diarmada or O'Diarmuid, meaning "son of Diarmuid." The name Diarmuid is derived from the old Irish words "deor" meaning "stranger" and "muid" meaning "protector" or "freeholder."

One of the earliest recorded mentions of the DERMOTT surname is found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the early 17th century. It references a Tadhg O'Diarmada, who was the chief of the Ui Diarmada clan in County Galway in the year 1243.

The DERMOTT name was particularly prevalent in the western counties of Connacht, with strongholds in Galway, Mayo, and Sligo. Some notable individuals bearing the DERMOTT surname in Irish history include Teige O'Dermott (1590-1659), a member of the Irish Parliament and supporter of the Catholic Confederacy during the Irish Confederate Wars.

During the Plantation of Ulster in the 17th century, many Irish families, including those with the DERMOTT surname, were displaced from their ancestral lands. As a result, the name began to appear in other parts of Ireland and eventually in other parts of the world as a result of emigration.

One famous bearer of the DERMOTT name was Roger de Coverley, also known as Roger DERMOTT (1717-1792), an Irish actor and playwright who achieved great success on the London stage during the 18th century. Another notable figure was Maurice DERMOTT (1776-1831), an Irish-born naval officer who served in the Royal Navy during the Napoleonic Wars.

In the 19th century, Michael DERMOTT (1828-1900) was a prominent Irish-American politician who served as the Mayor of Chicago from 1892 to 1893. Across the Atlantic, Sir Aubrey DERMOTT (1842-1922) was a British naval officer and author who wrote several books on maritime history and naval affairs.

Throughout its history, the DERMOTT surname has been subject to various spellings and variations, including Dermot, Dermod, Darmod, and Darmouth, reflecting the phonetic differences between English and Irish Gaelic. However, the core meaning and origin of the name remain rooted in its Irish heritage and the Ui Diarmada clan of Connacht.
