Lists of freeholders, voters and freemen can sometimes be a worthwhile genealogical resource to use. However, this can depend on the socio-economic standing of your ancestors. In Ireland, a large majority of the population was disenfranchised, primarily based on religious affiliation and land ownership.
When it comes to research on a particular name this can be negated by the monetary and economic success of particular people who had that name. The entry below comes from page 19 of a list of freeholders and freemen who voted in the 1770s in Dublin.
The vote itself took place from 13-30 December 1773 with names compiled from the original poll book. As usual, very few instances of the Buggy name is listed. In this case it is one, a Thomas Buggy who worked as a barber.
The reason for the election was to find a successor to the Marquis of Kildare who had become the Duke of Leinster. The candidates were Redmond Morres and Alderman Benjamin Geale. Redmond Morres received 1564 votes and Benjamin Geale received 1478. As a result Morres was elected to the Irish parliament by 86 votes.
