Eustachius is Greek in Origin.

From Latin Eustachius, the Latinized form of Greek Eustachios (Eustáchios), built from eu “good, well” + stachys “ear of grain,” the name means “fruitful, abundant,” evoking a good harvest. It is sometimes historically confused with Eustathius (Greek Eustáthios, “steadfast”), but the two have different roots and meanings.

The name spread across medieval Christendom through the legend of Saint Eustace, a Roman officer and martyr, and through Norman bearers such as Eustace II of Boulogne and the adventurer Eustace the Monk. In English it survives chiefly as Eustace, with medieval pet forms Stace and Stacey; the feminine counterpart is Eustacia. Other variants include French Eustache, Italian Eustachio, Spanish Eustaquio, Portuguese Eustáquio, Polish Eustachy, and German/Late Latin Eustachius. Though rare today, it endures in ecclesiastical and scholarly contexts - famously borne by anatomist Bartolomeo Eustachio (Eustachius), namesake of the Eustachian tube.
