What Casey means
Where Casey comes from and what it has meant to the people who carry it.
Casey came from Ireland. It grew out of the surname Ó Cathasaigh, formed on the Gaelic word `cathasach`, which means vigilant or watchful. The root is old. That Celtic layer sits under everything the name later became, long before any English speaker used it up front.
For generations Casey stayed a family name across Irish counties. In the nineteenth and twentieth centuries it moved into English use as a given name, taken up for boys and girls with equal ease. The meaning of watchfulness came along with it. A Casey answers to a word that once described a guard who does not sleep.
Picture the K page of a Polish class register. A Casey would sit there as a guest with an Irish past, a few desks from Kacper and Katarzyna, the surname turned first name.
The sense holds in plain words: watchful, `cathasach`, czujny.
