The expanded version of Slater’s National Commercial Directory of Ireland began in 1846 and was published intermittently for the rest of the century. It was very much the successor to Pigot’s Commercial Directory of Ireland which began publication in the 1820s. The entries below come from Slater’s publication and there are five Buggy men listed. They appear in entries for the counties of Kilkenny and Waterford.
