Origin
Meaning and history of Lastarza
The name Lastarza is believed to have originated from the Basque region of Spain, likely dating back to the medieval period. It is thought to be derived from the Basque words "lasta" meaning "load" or "burden" and "artza" meaning "bear" or "endure." This suggests that the name may have been given to someone who was perceived as a strong and hardworking individual, capable of bearing heavy loads or enduring difficult tasks.
While the origins of the name are rooted in the Basque language, it is possible that the name spread to other parts of Spain and Europe during the Middle Ages, when the Basque people migrated and interacted with other cultures. However, there is little historical evidence of the name being widely used outside of the Basque region until more recent times.
One of the earliest recorded instances of the name Lastarza can be found in the chronicles of a 13th-century Basque nobleman named Lope Garcia de Lastarza, who was a prominent figure in the Kingdom of Navarre. Another notable figure was Pascual de Lastarza, a 16th-century Basque writer and philosopher who authored several works on theology and ethics.
In the 17th century, a Spanish soldier named Juan de Lastarza fought in the Thirty Years' War and was known for his bravery on the battlefield. A century later, Pedro de Lastarza was a prominent architect who designed several churches and buildings in the Basque region, including the Church of San Sebastian in Bilbao.
Moving into the 19th century, Ignacio de Lastarza was a Basque politician and activist who played a role in the Carlist Wars, a series of civil wars in Spain over the issue of succession to the throne. He was a staunch supporter of the Carlist cause and fought alongside other Basque forces.
While the name Lastarza has its roots in the Basque region, it has since spread to other parts of the world, particularly in Latin America, where it is sometimes used as a surname. However, its historical significance and deep cultural connections remain firmly tied to the Basque people and their language.

FAQ
Lastarza: questions and answers
How many people in the U.S. are named Lastarza?
Name Census puts the figure at roughly 4 living Americans. We arrive at this by taking every SSA birth registration for Lastarza 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 85,688,585 US residents.
Is Lastarza a common name?
We classify Lastarza as "Very Rare". It ranks above 6.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 6 babies have been registered with this name.
When was Lastarza most popular?
The single biggest year for Lastarza was 1953, when 6 babies received the name. The fact that the average living Lastarza is about 79 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 Lastarza in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Lastarza a male name?

Is Lastarza still being used today?
Yes. The SSA still recorded Lastarza 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 Lastarza 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.
