The surname Cassady has its origins in Ireland, where it emerged as an Anglicized form of the Gaelic name "Ó Caiside" or "Ó Casaidhe". This name is thought to be derived from the Irish word "casadh", which means "twist" or "turn", possibly referring to a physical characteristic or occupation.
One of the earliest recorded instances of the name can be found in the Annals of the Four Masters, a chronicle of medieval Irish history written in the early 17th century. The annals mention a family called "Ó Caiside" from County Fermanagh in Ulster.
The Cassady surname is also associated with the Cassidy clan, a prominent family from County Fermanagh and County Donegal. In the 16th century, the Cassidys were among the most powerful clans in Ulster, holding significant lands and influence in the region.
In the 17th century, during the Plantation of Ulster, many Irish families, including the Cassadys, were dispossessed of their lands by English and Scottish settlers. This led to the spread of the surname throughout Ireland and beyond as families sought new opportunities.
One notable individual with the surname Cassady was Neal Cassady (1926-1968), an American writer and iconic figure of the Beat Generation. He was immortalized in Jack Kerouac's novel "On the Road" as the character Dean Moriarty.
Another well-known Cassady was Robert Cassady (1923-2013), an American baseball player who played in the Major Leagues for the Brooklyn Dodgers and the Boston Red Sox in the late 1940s and early 1950s.
In literature, the character of Frankie Cassady appears in the novel "The Grapes of Wrath" by John Steinbeck (1902-1968). Frankie Cassady is a young boy who befriends the Joad family during their journey to California.
The Cassady surname can also be found in historical records from County Fermanagh, such as the Hearth Money Rolls of the 1660s, which list several households with variations of the name, including Cassidy, Cassedy, and Cassady.
Lastly, one of the earliest recorded instances of the Cassady spelling can be found in the register of the Church of Ireland Parish of Devenish, County Fermanagh, where a burial record from 1695 mentions a "Cassady" family.
