HOW THE HOLIDAY CAME TO BE

An Irish patronymic that America turned into a first name.

INTRO

The oldest sense on record is keeping watch

National Casey Day carries a name whose oldest recorded sense is a duty rather than a quality. The Royal Irish Academy's dictionary of early Irish files the word under cathais and translates it "martial vigilance, watch".

The line the dictionary quotes to illustrate it is not a battle cry. It is an instruction: sleep but set a watch. Another citation under the same headword is glossed simply as "sentries".

From cathais comes the adjective cathasach, which the dictionary gives two senses at once, "vigilant; noisy". That adjective became the Old Irish man's name Cathassach, and Ó Cathasaigh, "descendant of Cathassach", is the Irish surname English flattened into Casey. The first element really is cath, battle, but the compound the dictionary records translates as a watch.

ORIGINS

Casey Day history

INTRODUCTION

America knows him as Casey Jones. Only the Jones part was his. The rest came from Cayce, Kentucky, the town his family moved to when he was thirteen, and he drove for the Illinois Central.

His train hit a stalled freight near Vaughan, Mississippi on April 30, 1900. He stayed at the brake and shouted for his fireman to jump. He was the only person killed.

CHAPTER 01

A nickname the country memorised

Wallace Saunders, a Black engine wiper at the Illinois Central roundhouse in Canton, Mississippi, cleaned the wrecked locomotive and wrote the first song about the man who had driven it. In 1909 two vaudevillians, T. Lawrence Siebert and Eddie Newton, copyrighted their own version, which the Tennessee Encyclopedia says became the basis for more than two hundred later ones.

The songs were not careful with him. Jones avoided saloons and was a faithful husband, and the hit version made him a hard-drinking rounder. In 1938 his widow published "Casey Jones, My Husband" as a rejoinder.

CHAPTER 02

Two more men who borrowed it

Twelve years after the wreck, a Brooklyn rookie named Charles Dillon Stengel won a poker hand during a rain delay. A teammate said "About time you took a pot, Kansas City", the other players started calling him K.C., and baseball called him Casey from then on.

The third Casey belongs to nobody. Ernest Lawrence Thayer's mock-heroic ballad ran in the San Francisco Examiner on Sunday, June 3, 1888, signed "Phin", wedged between the editorials and Ambrose Bierce's weekly column. People have claimed ever since to have inspired him, and towns have claimed to be Mudville, and none of it is settled.

CHAPTER 03

The name arrives late

None of this made Casey a common American first name for a long time. It first reached the Social Security Administration's five-a-year reporting floor in 1888, dropped off the list again the following year, and hovered near that floor for decades. It did not enter the top 100 boys' names until 1978.

Where National Casey Day itself came from, nobody wrote down. No founder, no organisation and no announcement can be traced, and no source explains June 16. What the day has instead is a name with an unusually long paper trail, from an Old Irish adjective to a Kentucky town to an American birth file that begins in 1880.

TIMELINE

Timeline

Casey at the Bat is printed

Ernest Lawrence Thayer's ballad ran in the San Francisco Examiner on June 3, signed with the pen name Phin.

The Cannonball hits a freight

Jones died at Vaughan, Mississippi on April 30, the only person killed in the collision.

A widow answers the song

Jones's widow published Casey Jones, My Husband, a rejoinder to the vaudeville version that had cast him as a rounder.

Jones goes on a postage stamp

The Post Office Department issued a 3-cent Railroad Engineers of America stamp carrying his portrait on April 29.

Casey enters the US top 100

The name reached 92nd among American boys, ninety years after the poem was printed.

The name reaches the girls' file

Five American girls were recorded as Casey, the first year it met the federal reporting floor on that side.

GOOD TO KNOW

Surprising facts about National Casey Day

The poem's hero was swapped for a rival within weeks

In July 1888 Jim Kennedy, editor of the New York Sporting Times, reprinted an abbreviated version with Casey renamed Kelly, for the Boston star Mike King Kelly, and Mudville renamed Boston.

Thayer was paid five dollars

Britannica records a $5 fee for the poem's initial publication. Thayer went back to running his family's wool mills while other people claimed to have written it, and made no serious effort to take the credit.

One actor recited it more than ten thousand times

DeWolf Hopper made Casey his signature turn and, by his own count, performed it over ten thousand times. Each delivery took him exactly five minutes and forty seconds.

For four years America gave the name to more girls than boys

In 1995, 1996, 1997 and 1998 the girls' count ran ahead of the boys'. Those are the only four such years in the 146 the federal birth files cover.

Two university presses disagree about Casey Jones

The Tennessee Encyclopedia calls him Jonathan Luther Jones and dates his birth to March 14, 1863. The Mississippi Encyclopedia calls him John Luther Jones and dates it to 14 March 1864.

WHY THIS DAY MATTERS

Why National Casey Day Matters

Revival

The low was 470 in 2018, and the count has not been back to it since.

American boys named Casey bottomed out at 470 in 2018, fewer than in any year since 1965, then rose in each of the six years to 1,099 in 2024 before easing to 1,072 in 2025. The girls' side ended the same stretch lower than it began, 228 in 2025 against 293 in 2018, its fewest since 1969.

Inheritance

The name records an ancestor, not a trait

Ó Cathasaigh means descendant of Cathassach, so what American parents now give as a first name began as a statement about somebody's ancestor. Casey started as a personal name in Irish, became a surname, and returned as a personal name in English.

Namesake

Some Caseys are named for the engineer

Behind the Name records that Casey is sometimes given in honour of Casey Jones, so a nineteenth-century nickname is one of the reasons the name gets chosen. The reference stops there, and so should anyone reading it: it accounts for particular families, not for the name's rise.

How to Observe National Casey Day

EDITOR'S PICK

Look the name up in the dictionary that holds it

The dictionary's entry for the root is a list of medieval citations, not a one-line meaning. Read the examples underneath the gloss and see how the word was actually used.

READ

Read Casey at the Bat out loud

The ballad was written for a newspaper's Sunday supplement and found its real life in performance. Read it to somebody rather than to yourself.

VISIT

Visit the Casey Jones Home and Railroad Museum

The museum in Jackson, Tennessee stands beside the engineer's own house. Its operator is plain that the locomotive on site is a version of engine 382 rather than the original.

CHECK

Check where your Casey sits in the birth data

The Social Security Administration publishes a file for every birth year since 1880. Find the year a Casey you know was born and see what the count was.

ASK

Ask a Casey which spelling they were given

Kacey, Kacie, Kasey, Kayce and Kaycee are all listed as variants of the same name. The answer usually comes with a story about roll call.
