Beatty or Beattie
(Scotland and Ulster)

The names Beattie and Beatty in Ireland are usually of immigrant origin having been brought to the country by settlers who arrived from Scotland especially during the seventeenth century. These names are also an anglicized form of the Gaelic occupation 'Biadhtach' meaning 'public victualler' and exist as such as Beatagh and Betagh in County Westmeath.
