Quickley-2 is a variant of the Irish surname Quigley. The original Quigley is an Anglicized form of the Irish Ó Coigligh, meaning "descendant of Coigleach", a given name derived from the word coigealach meaning "untidy" or "unkempt". The '2' in the surname may indicate a family branch or distinguish this line from other Quickleys. The name is ultimately rooted in the Uí Máine territory in Connacht. Note that the term "untidy" in Irish naming contexts often referred to unkempt hair, not moral character.
