My great-grandmother's name was Julia Cahalane and she was one of thirteen children. Raised in County Cork, Ireland. She immigrated to New York and then Chicago, sometime before the Great Depression. My great-grandfather's name was Daniel Hurley he was also from County Cork, Ireland. They had three daughters Eleanor, Margaret and Juliet. I do not know if these names I have listed are in any way related to the names you have listed. But Cahalane-Hurley is a very rare combination, so I just figured I ought to give it a reply. Please let me know if you have any additional info.
