Modern profile
Back to topModern surname records can be compared with neighbourhood classifications. For Cassedy, this points to the kinds of places where the surname is most concentrated today.
These neighbourhood labels describe areas, not individual people. They are useful because surnames often cluster through family history, migration, housing patterns and local work. A surname can be strongest in one type of neighbourhood even when people with that name live across the country.
The UK classification gives the national picture. The London classification is more specific to the capital, where housing, age profile, tenure and population mix can look quite different from the rest of the UK.

Origin
Back to topThe surname Cassedy is of Irish origin, derived from the Gaelic "O'Caiside" or "O'Caisaide," which means "descendant of Caiside." Caiside was a personal name in medieval Ireland, possibly originating from the old Irish word "cas," meaning "curled" or "twisted."
The name Cassedy can be traced back to County Fermanagh in Ulster, where the O'Caiside clan was based in the 12th century. The earliest recorded mention of the name appears in the Annals of Ulster, a chronicle compiled by medieval Irish monks, which references an individual named "O'Caiside" in the year 1192.
In the 16th century, during the Plantation of Ulster, many Irish families were displaced from their ancestral lands, leading to the widespread dispersal of surnames like Cassedy throughout Ireland and beyond. The name's spelling evolved over time, with variations such as Cassidy, Cassiday, and Cassady appearing in historical records.
One notable bearer of the Cassedy name was Patrick Cassedy, born in County Fermanagh in 1780. He was a prominent Irish Catholic lawyer and politician, serving as a member of the British Parliament for Dublin City from 1835 to 1837.
Another individual of historical significance was William Cassedy, born in County Tyrone in 1815. He was a noted Irish-American architect who designed several prominent buildings in New York City, including the Merchant's Bank building and the original St. Patrick's Cathedral.
In the United States, one of the earliest recorded instances of the Cassedy surname can be found in the Pennsylvania Archives, which mention a John Cassedy who served in the Revolutionary War in the late 18th century.
Edmund Cassedy, born in County Fermanagh in 1838, was a prominent Irish-American journalist and political activist. He co-founded the Irish World newspaper in New York City and was a vocal advocate for Irish independence and land reform.
John Cassedy, born in County Tyrone in 1845, was a renowned Irish-American civil engineer who played a crucial role in the construction of several major railroads and bridges in the United States during the late 19th century.
While the Cassedy surname may have evolved and spread across different regions, its origins can be traced back to the ancient Irish clans of Ulster, carrying with it a rich history and cultural heritage.
