Eustacio

Meaning & origin

Eustacio is a rare Spanish name with ancient Greek roots, first recorded in the United States in 1915. It reached its peak popularity in 1922, when it appeared occasionally in birth records, but it has remained extremely uncommon since then. The name has never ranked among the top 1,000 names in any year and has a stable trajectory of very low usage. Its rarity makes it a distinctive choice for parents seeking a traditional name with a strong historical and religious background. Though not associated with any particular U.S. state, the name's Hispanic heritage means it is more likely to appear in communities with Spanish-speaking populations.

Eustacio is the Spanish form of Eustachius, itself derived from the Greek name Eustathios, meaning 'stable' or 'firm.' However, some sources connect it to 'Eustachys,' meaning 'productive grain.' The name was borne by a second-century Christian martyr, Saint Eustace, and became common among Spanish-speaking Catholics. In the United States, Eustacio saw modest use in the early 20th century, particularly among Hispanic communities.
