Conley

Conley from O′Conghaile or Ó Conghalaigh is a surname of Irish or Manx origin. The anglicized forms Conneely, Connealy, and Cunneely emerged due to the loss of the "gh" sound, which lengthened the second syllable of Conghal. In Connacht, these forms are often shortened from McNeilly, derived from Mac Conghaile. Another possible origin is the West Cork name Mac Coingheallaigh or Ó Coingheallaigh, meaning "faithful to pledges." Historically, O'Connolly was a principal name of County Monaghan.
