A claim marked not established does not mean the name lacks a meaning or is not widely used — only that Namewise has not sourced and reviewed that content yet. Absence from a specific year or geography above does not prove zero use there either; official statistics only publish names above a minimum threshold.

Official popularity data is available for 3 regions, from 1996 to 2025. Highest recorded position: #214 in England and Wales in 2006. Source data last verified 2026-07-21.
