George Henry Bassett produced 7 Irish county directories in the 1880s: Antrim, Armagh, Down, Kilkenny, Louth, Tipperary and Wexford. Each provides useful history of the respective counties as well as lists of office holders, farmers, traders, and other residents of the individual cities, towns and villages.
The directories are naturally an invaluable resource for those tracing family history. However, there are a few points to bear in mind.
With respect to the last point, surnames which today begin with the “Mc” prefix, for example, were often formerly spelt as “M‘,”. For a list of some of the more common forename abbreviations used in the directory, see Forename Abbreviations.
