Originating from the United States, the name Tyrhianna is of recent coinage, attributed to author Mercedes Lackey's Elemental Masters series. It is a blend of 'Tyr', the Norse god of law and justice, and 'Ianna', derived from the Greek goddess Hecate. This unique moniker adds a touch of originality and intrigue to its bearer.
"Tyrhianna saw its peak popularity with 10 babies named each year in 2007 and 2008, followed by a steady decline to just 5 births in 2012."
