My maiden name was Dunn. When I was a child I received info in the mail saying the Dunn name (with variations such as Dunne, Dan, Danne, Dann) was traced back to the second century King of Ireland. Our house burned and I do not have this info still, but a family crest was even part of the info. As an adult, I read a book by Herbert W. Armstrong with the World Wide Church of God that spoke of the twelve tribes of Irael and the prophesy given to the tribe of Dan...that Dan would be like the serpents trail. Wherever those from the tribe of Dan have been, there lies evidence (like a snakes trail)....such as the Danube River. They were sea faring people who may have had a significant part in carrying the Arch of the Covenant to Ireland......Thus I was thrilled to find a link going so far back!
