I'm sorry I haven't replied in a while but I may have some information for you soon. I contacted some family in the area. It turns out that the Cosgroves I mentioned may be related...my Godfather Jack Cosgrove's father lived in the area and had a sister named Mary. The O'Connors you're looking for are not actually related to my family but my cousin knows where the family lived. I'll find out more when I talk to them in the next few days. We may not be able to give you birth dates etc. but at least some names to get you started...there is a local library that has some genealogy services that may be able to help you fit the pieces together.
It may be easier to have further contact through direct email.... kazoco at hotmail.
