Bohan is a unique and uncommon male given name of Irish origin. It is derived from the Irish surname Ó Buachalla, which means 'descendant of Buachalla'. Buachalla was a personal name that likely originated from the Irish word 'buachaill', meaning 'boy' or 'young man'. The name Bohan is often associated with County Cork in Ireland, where it has been traditionally used. It is also found in other parts of Ireland and among Irish emigrant communities around the world. In recent years, Bohan has begun to appear as a given name rather than just a surname, adding to its uniqueness.
"Bohan saw a spike in popularity from 2015 onwards, with the highest number of births recorded in 2017 and 2019 at ten each. However, it seems to have declined slightly recently, with seven births in both 2020 and 2022, before rising again to six in 2023."
