Our story of Kaycie
Ours, offered as ours. Casey has an unusually American afterlife: the railway engineer John Luther Jones was called Casey after Cayce, Kentucky, where he grew up, and the ballad about his 1900 crash made the name familiar across the country. The Irish surname is separate and older. Kaycie is a modern girls' respelling that could be from either, or from initials, and there is no telling which.
Meaningscholars disagree
vigilant, watchful
Irish Ó Cathasaigh is built on cathasach, generally read as vigilant or watchful. Separately the spelling may render initials. Which a family means is not recoverable, and both routes are documented in American naming.

Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method
