The short story
Orr is mainly a southwestern Scottish and Ulster-Scots surname. One strong explanation is Gaelic odhar, “dun,” “sallow,” or darkish complexion—a descriptive byname. English lines may instead come from Old Norse Orri, a byname meaning “black grouse.” Later migration carried the Scottish form into Ulster, where Orr became especially common. Ore and Orre appear as historical spellings. Nickname fits both the complexion and bird readings; confidence stays disputed because the two roots are independent even when the modern spelling matches.
