Morgan was a boys' name in Wales for a thousand years before American parents decided it belonged to girls. That shift happened in the 1980s and 1990s and was essentially complete by 2000. But Morgan's SSA data shows boys still receiving the name at rank #530, a reminder that the original gender assignment doesn't simply disappear.
The Welsh Foundation
Morgan comes from the Welsh elements mor (sea) and cant or gen (circle, completion, brightness), often interpreted as "sea-born" or "sea-circle." In Welsh tradition it was exclusively a male name, carried by kings and warriors. The Arthurian tradition gave us Morgan le Fay, a powerful sorceress — feminine, but clearly within mythology rather than everyday naming. For centuries in Wales, Morgan was a standard male given name equivalent to the English Robert in terms of frequency. SSA data: 45,110 total bearers (in male data), 1995 peak, current rank #530.
The Gender Shift
American parents began adopting Morgan for girls in the 1980s, possibly through the surname-as-first-name trend that swept through that decade. By the 1990s it was predominantly female in U.S. usage. Today, Morgan as a boys' name is most common in families with Welsh heritage or in communities where the historical male usage is known and honored.
The Counter-Argument for Boys
Naming a boy Morgan in 2026 is a statement: you know the gender history, you know how it reads to most American ears, and you're choosing it anyway. For Welsh-heritage families, that choice is an act of cultural reclamation. Compare it with Riley or Finley, names that made the same journey but have managed more neutral current status. Morgan for boys remains a defensible choice with strong historical roots and a genuinely beautiful meaning.
