I am very proud of the Tynan name, My ancestor's are from the central part of Ireland and the Tynan name is as common as Smith is in the United States. Please do not poke fun at it. I have never met anyone in the U.S. that had the same name, that was not related to me. There is a big car dealership in the Denver, Colorado area that has the name, but I have never met them. Maybe, they are related. I heard in Ireland, that the name may be related to having dark hair, We all have dark hair in my family???
