Countless individuals give huge amounts of their free time towards making genealogical records more accessible to those conducting family history research. One such person is John Hayes at his website failteromhat.com.
On this site he has various transcriptions and scanned pages from censuses, directories and books. One example is Pigot and Co.’s 1824 Provincial Directory of Ireland. A number of examples of the Buggy/Buggey name can be found within. In Kilkenny City there are three men listed: 
Dyers Buggey, Michael (and clothier) Irishtown
Leather Sellers Buggey Wm. Coal -market
Rope Makers Buggey, William High St.
