MONAHAN Family History

Recorded in several spellings including Monaghan, Monahan, and more properly O'Monahan, and sometimes Monk, although this is also an English name, this is an Irish surname of great antiquity. It derives from the pre 10th century Gaelic word 'manachain' meaning a monk. However it would seem that the first chief from whom all later nameholders descended, was perhaps both monk and a mighty warrior of the 9th century. A case of mistaken identity or something more sinister? The history book are silent, but as we know from the famous tales of Robin Hood, the Friar was not above a little swordsmanship when the necessity arose...
