Hello Diane Shaw, Re your gggda, have you looked into the 1821 census of Navan in the Co. Meath Heritage Center. Most of the 1821 Census was destroyed in the 1922 Fire in Dublin but records of two barionies remain. I collected all of the Byrne, Burn folks listed, (over 100) Three well may have been your folks listed there too. Good luck. Bill Byrne of Palos IL
