I have Irish roots, but mine are of the early 1800's. I do not know nearly enough of my Irish ancestry to know if any cousins may have participated in the Irish Civil War. One of my great-great-grandfathers, Thomas Riley, came to America in the 1850's and lived until 1915. On the 1930 census, his son John P. Riley listed Thomas's birthplace as "Irish Free State":

Records created in other parts of the world are often far more complete than many of us can find in the United States. I have worked with records in West Prussia and Denmark and have had great success.
Martin found he had ancestors that had social and moral convictions they fought for, as does Sheen. I think a big part of researching your family is finding where you fit on your tree. It's hard to say if it is nature or nurture that created our non-physical traits. But it is nice to find family like you.
Good start, NBC! Can't wait until next week!
