I have intermarried ancestors from Wicklow/Wexford (immigrated to N. America ca. 1820-1870)with these names. One notation in records say a Chapman was from "Dunbur, County Wicklow." I can't find it on a map or in parrish lists. I had the same problem for awhile for a Johnston in County Wexford with "Donamore" which I think is "Donaghmore" in north County Wexford. Any help with "Dunbur" or the family names appreciated.
