About Oneal
Oneal is a masculine name derived from the Irish surname Ó Néill, meaning 'descendant of Niall.' The original Gaelic name Niall possibly means 'champion' or 'cloud.' As a first name, Oneal gained modest usage in the United States during the 20th century, often as a variant spelling of O'Neal. The name carries strong Irish cultural associations, connecting to one of Ireland's most powerful ancient families who claim descent from Niall of the Nine Hostages, a legendary High King of Ireland. While never reaching widespread popularity, Oneal appeals to parents seeking a name with Celtic roots and historical significance. Its straightforward pronunciation and spelling make it accessible despite its relative uncommonness.
Oneal is also given to girls.
Pronounced oh-NEEL.
As of October 2026, Oneal ranked #11642 in US births in 2025 SSA, peaked at #784 in 1935.
