O'Hanfy, or O'Hanify or Hanvey, is however, quite a distinct name - O hAinbhith in Irish. Their territory was in the same part of the country. The pressure of the Anglo-Norman invasion pushed the O'Hanraghtys westwards into Co. Monaghan, and in the twelfth century they settled near the modern town of Castleblaney. Father Patrick Hanratty , a Franciscan of note in the first half of the seventeenth century, was a native of Co. Louth. And this is the form of the families living in Ireland todays.
Any connection is likely but unproved.
In France another form is existent. A member of the noble branch of the Hanretty is told to have played a certain roll during the French Revolution abt. 1790, and could be traced back to an Hanratty from Ireland, too. The main ancestors, means the first emigrants to the continent, had been convicted in Ireland or England, and had been decided to be shipped to the penal colonies where they stayed. The only form Hanrotty is to be found in Germany.
