Phyllis,Londerry perhaps? or Derry as its sometimes refered to.Donegal is pretty close--would you by any chance be going to a big gathering of Doherty families? Just curious. What church are you going to try to get inf from? My grandparents were baptised at Sacred Heart in Co Donegal(Cardonagh)
One day I still think we may find some connection--we'll see. Have fun and good luck!!!
