Buggy/Ó Bogaig(h) [pronunciation bug-ig/bog-ig] is an Irish name that is associated with the bordering counties of Kilkenny and Laois. Historically, the name is mostly found in the areas of north Kilkenny and south/south-east Laois. The renowned Irish genealogist, Edward MacLysaght (1887-1986), derives the meaning of the name from ‘bog’, the Irish word for soft. Rev. Patrick Woulfe regards the name as a phonetic anglicisation. Most Irish surnames were anglicised in the period 1550-1600, with little regard shown to the original Irish spelling as they were written down. Up to the mid 1900s the name was spelt Ó Bogaig, indeed this is the spelling in Sloinnte Gaedheal is Gall. Current spellings show the addition of an ‘h’, giving Ó Bogaigh. Both, of course, are equally valid.
