for Jennifer (Blayney) Harden. I read your message asking for help to find Blayney book going back to 100BC in Ireland. I'm sorry to have to say that I cannot think that any family tree could possibly go back to 100BC. The Blayney family tree has been traced back to 970AD and the family was originally Welsh, not Irish. One branch of the Welsh family went to Ireland in 1621 with the Earl of Essex and became the Baron Blayneys of Monaghan. My mother is a Blayney and we have a copy of the family tree going back to 970AD (with some gaps down the line). If you would like any information please contact me.
