Origin
Meaning and history of Seabrook
The given name Seabrook is an English name that originated in the late 16th century or early 17th century. It is a locational name derived from the combination of the words "sea" and "brook," referring to a small stream or watercourse that flows into the sea. The name likely originated in coastal areas of England where such geographic features were common.
One of the earliest recorded instances of the name Seabrook can be found in the parish records of St. Mary's Church in Bury St. Edmunds, Suffolk, England, where a person named John Seabrook was mentioned in 1613. This suggests that the name was already in use by that time.
In terms of historical references, there are no known mentions of the name Seabrook in ancient texts, religious scriptures, or major historical records from before the 17th century. However, the name's connection to coastal locations and waterways may have been influenced by the importance of maritime activities and trade in England during that period.
Throughout history, several notable individuals have borne the first name Seabrook. One such person was Seabrook Wilkinson (1725-1796), an English merchant and ship owner who played a significant role in the trade between England and the West Indies during the 18th century.
Another notable Seabrook was Seabrook Fowler (1821-1898), an American politician and lawyer who served as a judge in the New York Supreme Court in the late 19th century.
Seabrook Jacobs (1872-1941) was an American architect known for his work in New York City, including the design of the Marymount School building in Manhattan.
In the literary world, Seabrook Pyle (1888-1965) was an American writer and journalist who gained recognition for his travel writing and reporting on various cultures around the world.
Lastly, Seabrook Jones (1920-2001) was an American military officer who served in World War II and later became a prominent businessman and philanthropist in the state of Georgia.
These examples showcase the diverse backgrounds and accomplishments of individuals who have carried the name Seabrook throughout history, reflecting its roots as an English locational name with ties to coastal regions and waterways.

FAQ
Seabrook: questions and answers
How many people in the U.S. are named Seabrook?
Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Seabrook going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 68,550,868 US residents.
Is Seabrook a common name?
We classify Seabrook as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.
When was Seabrook most popular?
The single biggest year for Seabrook was 1983, when 5 babies received the name. The fact that the average living Seabrook is about 41 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Seabrook in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Seabrook a male name?
Yes, 100.0% of people registered as Seabrook in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Seabrook still being used today?
Yes. The SSA still recorded Seabrook in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Seabrook can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
