Hi Jan, you will have to get a map of Ireland to see proximity of counties, etc. I do not know.
William Quaid was the son of Andrew Reese Quaid and Nancy/Agnes McMillen. His siblings were John, Robert and James. William married Eliza Slater in 1866 and is buried in the Old Moore's Mills Cemetery in Baillie, St James Parish, Charlotte County, NB. His children were William who died in infancy, John, Mrs Matilda Brummond, Mrs Mary Mann and Mrs LaForest Robinson. (He had daughter Eliza, but that may have been "Mrs LaForest" Robinson.) William's wife Eliza died in 1883, and he remarried in 1886 Miss Mary Dunn and had no further children with her.
