Searching for Pendergast family and De David family

I am tracing my maternal grandmother's family line. We have a baptism record for a Patricius Pendergast born in 1794 and baptized November 25, 1794 in Carrick-on-Suir. His parents names were Renfred Pendergast and Anna De David. I am looking for further information on Patricius and Renfred and Anna. I hope to travel to the area (but likely not till summer 2022) at this point.
