McCausland

McCausland (''Mac Ausaláin'' in Gaelic), meaning "Son of Absolom" is a surname of Irish origin; there is also a clan of this name in Scotland. The family claim descent from the Cenel Eoghain race in Derry 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'. Provided by Wikipedia
