This article looks at how common Fitzpatrick is as a last name in Ireland and the United States from the 19th century to the present day.

You’ll learn the meaning and origins of the Fitzpatrick surname while exploring some notable and famous people that held it.

I use census records, emigration lists, and military archives to uncover fascinating patterns. If you’re studying your genealogy, check out my sources at the end of the post so you can do your own research.

How Common Is Fitzpatrick As A Surname In Ireland?

Ireland does not disclose current statistics on surnames in much detail. The most that we get is the top ten last names in birth registrations for the previous year. Fitzpatrick

However, an Irish genealogist studied the top one hundred surname numbers in Ireland between 1992 and 1997. Seán Murphy based his research on telephone books. This isn’t as accurate as a census but gives a good approximation.

Fitzpatrick was ranked 60 in the top one hundred names in this decade with a total of 12,700 entries.

This graphic shows how it ranks compared to the 1st, 33rd, 66th, and 100th entries in the survey:

Fitzpatrick In The Early 1900s

The only full censuses that are publically available in Ireland are from 1911 and 1901. Prior decades were either destroyed through government action (to reclaim storage space) or by a catastrophic fire during the Irish Civil War.

So, let’s focus on the early 1900s.

I used online archives to calculate the total numbers by surname. I consider these estimates due to some percentage of transcription errors. So, I’ve rounded the numbers to the nearest fifty.

There were 9,600 residents named Fitzpatrick on the island in 1911.

Ten years earlier, Fitzpatrick had about 10,000 residents in the 1901 census.

Population Estimates In The 1890s

A study of Irish surnames was conducted in 1890 by the head of the Civil Registrations Office. It was published as a “Special Report on Surnames In Ireland.”

The survey estimated that there were about 11,100 people named Fitzpatrick in the country.

Emigration To America After The Irish Famine

The Irish diaspora is large and widespread with a significant number of people emigrating to other parts of the globe. The destinations traditionally have been England, the U.S., Canada, and Australia. Emigrants were driven by various factors like political unrest, poverty, and food scarcity.

The peak of this migration was driven by what’s known as the Great Irish Famine, a devastating event spanning from 1845 to 1852. Potato blight had a catastrophic effect on Ireland, wiping out the primary food source for a significant portion of the population.

I reviewed the Fitzpatrick name in the shipping passenger lists arriving in New York during this period. The departures were from both Ireland and England.

This picture shows how the numbers rose and fell in the years after the famine:

How Common Is Fitzpatrick As A Last Name In The U.S.?

Based on the 2010 U.S. census, the name Fitzpatrick ranks about 852 among Irish names in America with 40,449 bearers.

Although the 2010 census has exact numbers and rankings, the rank I assign here is my estimate. If you’re curious about how I got there, here’s a brief explanation…

Estimating Rank In The United States

Historically, some Irish families with Gaelic surnames took English-sounding names as translations under the influence of colonization.

As these names also have English origins, they will have been brought to the United States by both British and Irish immigrants. Because the census doesn’t ask about specific European origin (e.g. England vs Ireland), it’s impossible to identify the proportion with Irish heritage.

I reviewed the census to identify which names are predominantly Irish in origin. In order to estimate the relative rankings of “Irish” names, I’ve mostly excluded surnames that have varying origins.

Fitzpatrick In Historic Times

It’s interesting to look at how the numbers of a surname change over time in a relatively young country like the United States. These changes can reflect the broader demographic shifts within the nation. It’s not just migration from outside. It’s also birth rates, improved child mortality, and people living longer.

The historic census records have been transcribed and digitized. I used online archives to run counts of surname populations.

But the totals can’t be exactly accurate due to transcription errors. So, I’ve rounded the numbers to the nearest 50 in the graph below.

This picture shows the numbers every twenty years from 1860 to 1940:

These are the numbers in the graph:

  • 1860: 7,400
  • 1880: 13,850
  • 1900: 18,250
  • 1920: 21,000
  • 1940: 23,950

Fitzpatrick In World War II

Approximately 8.3 million men and women joined the United States Army during World War II. Many had Irish ancestry. Some had been born in Ireland before leaving the country.

There were registration records for 1,526 soldiers named Fitzpatrick who enlisted between 1938 and 1946.

There were 24 who were born in Ireland.

Fitzpatrick Surname: Meaning And Origin

Fitzpatrick comes from the Gaelic “Mac Giolla Phádraig”. The Gaelic word mac means “son of” and giolla refers to a servant. So, the full name means “son of the servant of Saint Patrick”.

Often with Irish names, the “Fitz” indicates that it was brought in by Norman knights as part of the Norman Invasion of the late 12th century. However, Fitzpatrick is different.

When the British government put increasing pressure on Irish families to take English forms of their name, some families with the name Mac Giolla Phádraig adopted Fitzpatrick instead.

Famous Or Historic People Named Fitzpatrick

Here are some notable people with the family name:

  • Benjamin Fitzpatrick (1802 – 1869): an American politician in the Democratic Party, he was the eleventh governor of Alabama.

  • Daniel Fitzpatrick (1891 – 1969): an American newspaper cartoonist who won two Pulitzer Prizes for his work. He spent 45 years with the St Louis Dispatch.

Internal Research

Some of the population numbers are based on my own research and calculations using online archives. I’ve rounded those numbers to the nearest 50 to account for transcription errors and other technical issues with online databases of this type.
