If I were you, I'd look for Burkes and O'Connors in the same civil parishes, then see which of the corresponding RC parishes have been filmed by the LDS back to the 1840s and 50s, when Julia and her brothers were born, looking for their baptisms. People often married outside their townlands, less often outside their parishes. Go to Irishtimes.com/ancestor to get civil and RC parish maps. Diane
