I have a Patrick Dornan born about 1744 in Ireland, he would be my Great Great Great Great Great Grandfather. He had four sons that we know of 1.John 2.James 3. Henry 4.David. We don't know Patrick's wife's name either. John was born June 6, 1766 in Ireland but we don't know the birth dates of the other three brothers. Prior to 1787 John and James migrated to the America but it is believed that Henry and David were doctors and that they remained in Ireland.
