I have found it very difficult to search for the O'Neils. The children I have found for James O'Neil and Elizabeth Cummings are Margaret (b. 1827), John (b.1828), James (b. 1830), William (b. 1832), Elizabeth (b.1834), and Helen (b. 1836). Sorry to say I have not found a Mary Ann in this family or Murphys or Curletts.
I noticed that you have middle names for James and Elizabeth. Might I ask where you found this information? I have not been able to find their vital records and would very much appreciate any leads you could give me.
