The book "Shamrocks and Shepherds: The Irish of Morrow County" by John F. Kilkenny is a wonderful resource. I have the book as well as the one by Michael Whelan, "The Parish of Aughavas". Both are great. The O'Briens and Campbells are mentioned on page 49 in "Shamrocks and Shepherds". I am lucky enough to have early photos of these brave pioneers.Members of my O'Brien family still live on a ranch in Heppner, Oregon. Gail Moran
