Likely a modern form related to Jerica or Jericho; Jericho is a Hebrew place-name often linked to 'city of the moon.'
Jerricha is likely a modern form related to Jerica or Jericho, with the place-name Jericho itself often linked to the city of the moon. That gives the name an indirect biblical and geographic resonance even when its present-day form is inventive.
The name feels contemporary and somewhat playful, with a recognizable first-syllable anchor and a more unusual ending. Jerricha belongs to the modern habit of expanding familiar sounds into new names. It has a distinctive look and a lightly exotic feel without being difficult to pronounce.
