What two years of headlines did to a common name

In 1997, Monica was the 79th most popular name given to American girls. Two years later the name was going to nearly half as many of them. National Monica Day, held on July 18, belongs to a name that fell harder than anything around it.

Not one of the 423 most popular girls' names of 1997 dropped further over the next two years. The count went from 4,223 to 2,134. Only at 424th on that list does a name appear that fell harder.

Nor was it a lull in the birth rate. Across the same two years, the number of American girls given a top-1000 name rose 1.9 percent. Something happened to this name in particular, and the women who already carried it noticed first.

ORIGINS

Monica Day history

INTRODUCTION

Augustine of Hippo writes about his mother all through the Confessions. He names her exactly once.

The naming sits in Book IX, where he asks readers to remember at the altar "Monnicae, famulae tuae, cum Patricio, quondam eius coniuge." Monnica, with two n's. The other twelve books never use it.

CHAPTER 01

From Thagaste to a courtyard in Ostia

She was born at Thagaste and died at Ostia in 387, waiting for a ship back to North Africa. Her husband Patricius was a pagan who reportedly had a violent temper. Augustine was seventeen and studying rhetoric in Carthage when his father died.

Her funerary epitaph was written by Anicius Auchenius Bassus and survived in old manuscripts, but the stone itself vanished. It came back in the summer of 1945, when two boys digging in a courtyard beside the church of Santa Aurea hit it. Her tomb had already been moved to the Basilica of Sant'Agostino in Rome.

CHAPTER 02

Into English by way of a novel

The name reached general English use in the 1700s. Anthony Trollope then handed it to a memorable minor character: Miss Monica Thorne of Ullathorne, who turns up four times in Barchester Towers in 1857. Reference works tend to point instead to the following year's Doctor Thorne, where she is named only once.

CHAPTER 03

Thirty-four years in the American top hundred

Monica entered the American top 100 in 1964 and stayed there every single year until 1997. Those thirty-four years are the only ones it has ever spent that high.

Then January 1998 arrived. Ann Carrns opened a Wall Street Journal report that October, syndicated in the Santa Cruz Sentinel, with a plain line: "Ever since Monica S. Lewinsky burst into the headlines in January, life has been trying for Monicas both famous and obscure." The name went from 79th in 1997 to 105th in 1998, and it has never been back inside the top 100.

The holiday has none of that paper behind it. Four holiday-listing sites were checked against the Internet Archive.

Not one holds a saved copy of a Monica page, though their other holiday pages are archived years back. The name has a paper trail running back to the fourth century, and its holiday has none.

I made an appointment to have my hair cut, and when I showed up, they said, 'we've been laughing about your name all week.' But I think I'll keep my name, anyway.
Monica StarrQuoted in the Wall Street Journal, 1998
The first thing they'll say if I introduce myself as Monica: 'Oh, Monica Lewinsky.' And then there is a little giggle or something like that. And after a while, it gets kind of irritating. It really does.

WHY THIS DAY MATTERS

Why We Love National Monica Day

FORECAST

Declared faded in 1995. It ranked 87th that year.

A 1998 newspaper report quoted the baby-name authors Linda Rosenkrantz and Pamela Redmond Satran, writing in 1995, as saying the name had "just about faded away at this point." Federal files put Monica at 87th that year, still inside the top 100, on 3,970 American girls.

LANGUAGE

The name changes shape as it crosses borders

French and Dutch speakers say Monique, and Estonians write Moonika. Spanish has Mónica, Brazilian Portuguese has Mônica, Monika runs across Germany and Poland, and Scandinavians shorten the whole thing to Mona.

PATRONAGE

Her saint still has a working brief

Monica of Hippo is listed as patron of married women, difficult marriages, disappointing children, victims of adultery, victims of verbal abuse and lapsed Catholics. She is also patron of the Berbers, the people her own name may have come from.

How to Celebrate National Monica Day

EDITOR'S PICK

Read the one line where Augustine names her

The line is in the ninth book of the Latin Confessions, in a plea that she be remembered at the altar. The rest of the work never repeats it.

LOOK

Look up the year you were born

The Social Security Administration publishes a file for every year since 1880 listing each name given to at least five American babies. Find the year that matters to you and see where Monica sat.

ASK

Ask a Monica what 1998 was like

Reporters that year found women named Monica fielding the same joke at the deli counter and the hair salon. It makes for a better conversation than a card.

VISIT

Visit a place that carries the name

The California coast was given her name in 1769, and the city of Santa Monica grew there afterwards. Rome keeps her tomb, and Ostia keeps the church where her epitaph turned up.

SEND

Send the day to a Monique or a Monika

The name changes spelling at almost every border, so its day travels further than most. Pass it on to anyone whose passport spells it differently from yours.

Test your knowledge

How well do you know National Monica Day?

1 / 8

Which origin do reference works give for the name Monica?

Answer

No. It is an unofficial observance, and a full-text search of the US Federal Register returns no document carrying the name, so July 18 is a normal working day.
