Family name origins & meanings

  • Scottish and northern Irish : probably a variant of MacAuslan, which according to Black is an Anglicization of Mac Ausaláin ‘son of Absolom’, from the name of an early 13th-century cleric. However, there may rather be an underlying Gaelic personal name, possibly Caisealán, meaning ‘little one of the castle’.
