Did you ever find those O'Rourke's in Eire. My ancestor James Rorke was born in 1845 in Roscommon. He was one of a large family of boys some of whom went to America and Edinburgh. James's parents were Thomas O'Rourke and Ann Keefe, He was a mason by trade and never left Eire. I think they Thomas and Ann may have been born around 1780 in Roscommon. They were Gallic speaking being part of the old Irish families in this area. they married Guihan or Wynns, Gillhooly's and Earleys.
