Thank's for all the O'Beirne answers out there! I've spent a great deal of time tracking them though the US and have no earthly idea how to get back to Ireland. I have been lucky on a few instances - dumb luck really. My Great Grandparents were Patrick O'Beirne 1825-1907 married to Mary Hopkins. They had James O'Beirne 1845-?, Bridget O'Beirne 1847 -? and John O'Beirne 1848-1922, Charles O'Beirne 1849 - 1924 in Denver, Patrick O'Beirne, Jr. 1849 - 1929 in Chicago (Patrick was my Great Grandfather), Frank O'Beirne 1852-?. Until recently I was never aware of Frank or James. I do know that Charles, Patrick and John came to the US. Patrick came when he was 15 so that had to be around 1864 or 65? I would think he traveled with his brothers but he may have come later. I know that Bridget stayed in Ireland and married Thomas Cooney. They lived out their lives in Roscommon. If this clicks with anyone, I'd love to hear from you. Thanks, Patty O'Beirne
