Bradley is an English surname derived from a place name meaning "broad wood" or "broad clearing" in Old English.
Like many English surnames Bradley can also be used as a given name and as such has become popular.
It is also an Anglicisation of the Irish Gaelic name O’Brolachán (also O’Brallaghan) from County Tyrone in Ireland. The family moved and spread to counties Londonderry, Donegal and Cork.
