Thanks for the post, Margaret. I'd be grateful if you'd be able to share dates and names of the wives of the O'Briens in your tree. Am trying to figure out still where they fit in.

The don't appear to to match up with the James O'Brien and Joanna McCarthy family of Sam's Cross who settled there in probably the 1840s (my relatives). There were some other O'Briens listed in Tullineasky - Jeremiah and Anne with a son Denis who was born in 1832.
