Parent’s name
Sloan surname meaning
An Irish and Scottish Gaelic surname, Ó Sluaghadháin, “descendant of Sluaghadhán,” a diminutive of Sluaghadh, “raider.”
The short story
Sloan is an Irish (especially Down and Antrim) and Scottish shortened Anglicization of Gaelic Ó Sluaghadháin, “descendant of Sluaghadhán.” The personal name is a diminutive of Sluaghadh, “raider” or expedition-leader, so the surname is a clan-style patronymic built on that byname. Sloane and Slone are common variants; Slowey comes from a related Sluaghadhach form found in Monaghan and Ulster. The name is one of the few Ó surnames historically used in southwest Scotland. Parent’s name fits the Ó-descendant structure, and the raider-diminutive etymology is high confidence.
