Henchy is an uncommon given name of Irish origin, derived from the surname 'Henaghan', which was an Anglicized form of the Gaelic 'Ó hEanchaidh'. This surname was originally borne by a sept from Westmeath in Ireland. The name Henchy has been quite rare throughout history and is still not widely used today, contributing to its unique appeal.
The name Henchy has seen varying popularity over time, with a notable peak in recent years. After starting the 90s with just 5 births annually, it reached a high of 21 births in 2014 and 2018 combined. However, it has since stabilized around the mid-teens to low-twenties mark per year, suggesting a consistent but not overwhelming demand for this name.
