If a match, there is a marriage for a Mary Condron, daughter of Daniel, in Manchester in 1901. He is noted as a porter and living at 19 Brunswick Place. She married a James Rayner (or Raymer) of 3 Brunswick Place, a fitter by trade. Married in the Established Church, which was Anglican (Church of England), and not Catholic.
1901 census shows a John Condron, also of Queens County (New Town), working in a coal miner in Co. Durham. Born about 1876, he is the right age to be another son of Daniel's.
