McCausland

McCausland (Mac Ausaláin in Gaelic), meaning "Son of Absolom" is a surname of Irish and Scottish origin. The family claim descent from the Cenel Eoghain race in County Londonderry and Tyrone, a branch of the Ui Neil.

Alternatively, the surname may be an Anglicization from a Gaelic name, as was the case with many Irish surnames, changing to sound more English over the centuries. The surname "Mac Ausaláin" may have an underlying Gaelic personal name, possibly Caisealán, meaning ‘little one of the castle’.
