Bohan — Descendant of the Little Victorious One

Bohan anglicises Ó Buadhacháin, built on buadhach, ‘victorious’ or ‘triumphant’ — Buadhachán itself a diminutive, giving something close to ‘little victorious one.’ The earliest documented record of the surname places it in County Cork, in the Irish Fiants, the surviving administrative records of Tudor-era Ireland.

A name built from a word for victory itself, first caught on paper in a set of centuries-old Tudor administrative rolls.
