The history of the last name Deady

The surname Deady originated in Ireland, with the earliest known records dating back to the 11th century. It is derived from the Old Irish Gaelic word "deidadh," meaning "to delay" or "to hinder." This suggests that the name may have been given to someone who was perceived as slow or deliberate in their actions.

The name Deady is most commonly associated with County Cork in the province of Munster, Ireland. It is believed that the name first appeared in the Barony of Muskerry, a historic region of County Cork. The Deadys were among the prominent families in this area during the Middle Ages.

One of the earliest recorded mentions of the name Deady can be found in the Annals of Inisfallen, a chronicle of medieval Irish history. The annals refer to a "Diarmaid Deady" who lived in the late 12th century and was involved in a conflict between rival Irish clans.

During the 16th and 17th centuries, the Deady family played a notable role in the Gaelic resistance against English rule in Ireland. Several members of the family were influential leaders and soldiers, including Donal Deady, who fought in the Nine Years' War (1594-1603) against the English crown.

In the 18th century, a prominent figure bearing the Deady name was Patrick Deady (1700-1778), a wealthy landowner and merchant from County Cork. His descendants continued to be influential in the region for several generations.

Another notable individual was Daniel Deady (1810-1887), an Irish-born judge who served on the United States District Court for the District of Oregon. He was appointed to the bench by President Ulysses S. Grant in 1871.

Other notable individuals with the surname Deady include:

1. Michael Deady (1824-1898), an Irish-American lawyer and politician who served as a member of the United States House of Representatives from New York.
2. Kathleen Deady (1926-2022), an American actress and singer who appeared in numerous films and television shows throughout her career.
3. Brendan Deady (born 1959), an Irish hurler who played for the Cork senior hurling team and won two All-Ireland championships.
4. Patrick Deady (born 1973), an Irish professional golfer who has competed on the European Tour and won several tournaments.
