The Tithe listings date from the late 1820s/early 1830s. If you go to the National Archives site, you can search for Mulloy/Molloy records in Whitechurch civil parish. You have to search Mulloy separate from Molloy but you will find ten records in Whitechurch parish. None were in Poulmaloe townland.
