Cassiday

The surname Cassiday is of Irish origin, derived from the Gaelic name "O'Caiside." It is believed to have originated in County Fermanagh, Ireland, during the Middle Ages.

The name Cassiday likely stems from the Gaelic word "cas," meaning twisted or curly, and may have been used to describe a person's physical appearance or personality. It could also be related to the word "caisidh," meaning a pathway or causeway.

One of the earliest recorded instances of the Cassiday name can be found in the Annals of Ulster, a chronicle of medieval Irish history. In 1456, a reference is made to a man named "Donough O'Caiside," who was involved in a conflict with the O'Neills, a powerful Irish clan.

In the late 16th century, during the Plantation of Ulster, many Irish families, including the Cassidys, were displaced from their ancestral lands. Some Cassidys migrated to other parts of Ireland, while others fled to Europe and the Americas.
