Sheamus

Meaning & origin

Sheamus is an Irish form of James, carrying the meaning 'supplanter.' It first entered U.S. baby name records in 1981, a late arrival compared to many classic names. Its peak popularity came in 2014, though it never broke into the top 1,000 nationally. Since 2013, its trajectory has been falling, reflecting a broader shift away from traditional Irish names in favor of shorter, more modern choices. In 2025, the name was given to roughly 1 in every 284,679 newborn boys, placing it far outside the mainstream. Despite its low rank, Sheamus retains strong cultural ties to Ireland, often evoking an authentic Gaelic heritage. No U.S. state has ranked it highly enough to be listed in top-state data, indicating its rare and scattered usage across the country.

Sheamus is the Irish form of James, which itself derives from the Hebrew name Ya'akov (Jacob). The name entered Irish through Latin (Iacomus) and became Séamus, anglicized as Sheamus. In Ireland, it has been used for centuries, often associated with traditional families. Outside of Ireland, it gained moderate recognition in the late 20th century, especially after the 1990s.
