Fethard & Moycarkey ancestry Denis Leahy 1811 and Kearneys

Hi - I found my great great grandfather Denis Leahy's baptismal in Fethard in 1811but those of his siblings in Moycarkey. We had always been told he was from Thurles. His parents were Denis Leahy & Mary Kearney. He had 5 siblings, I have found baptismal info on two brothers, Andrew and Jeremiah. I visited both Moycarkey and Fethard last month, but found no clues. Would like to connect with others researching this family.
