We never went to the island because we found information in Ireland indicating that our James Tierney was likely froma very small town, Roos (aka Roose), in County Mayo. I am in touch with Andy Tierney of County Clare, whose great-grandfather was the James Tierney of Roos. His wife's name is unknown, so we are not completely certain. We're still working on it. James T of Roos had other children: Patrick, Sarah, another girl, & possibly a brother, Peter.
