Paul--just discovered your post. I was interested in your reference to the "route area" in Ireland. I am a McCaig by birth from Texas. I can only prove back to Alabama circa 1832, but believe my ancestor John Smith McCaig's father was Samuel Smith McCaig born in Tennessee. I have not been able to track back to Ireland as yet. My maternal line is the Meares of County Westmeath. My husband's line is the Nannerys from County Longford.
