Loghan is a spelling variant of Logan, from a Scottish surname and place name meaning 'little hollow.'
Loghan is a variant spelling of Logan, a name rooted in Scottish Gaelic geography. The original form, Lagán or Lagan, refers to a "little hollow" or "low-lying meadow," the kind of gentle depression in the landscape common to the Scottish Highlands and often marked by a stream or boggy ground. It began as a place name, then became a clan surname — the Logans were a notable Scottish family with a storied, sometimes turbulent history — and only in the twentieth century migrated into the given-name pool.
Logan's rise as a first name was gradual and then explosive. It appeared occasionally as a given name through the mid-century, then surged in the 1990s and 2000s on both sides of the Atlantic, carried partly by the cultural appeal of surnames-as-first-names and partly by the Marvel character Wolverine, whose human name is Logan — a fictional association that gave the name an edge of rugged, self-contained strength without being overtly aggressive. By the 2010s it was a top-five boys' name in the United States and Canada.
The Loghan spelling diverges from the standard by inserting an h after the g, a pattern seen in Irish Gaelic orthography where silent or semi-silent h's appear frequently. Whether chosen for visual distinction, family heritage, or simple aesthetic preference, Loghan signals an individualizing impulse within a very popular name — keeping the familiar sound while making it unmistakably singular on paper.
