This is just a place holder for a local history page.
There is a ballyvoyle history group facebook page https://www.facebook.com/Ballyvoyle/
Obviously if you are researching the history of the area online search for both Ballyvoyle and Ballyvoile. For example the Waterford Museum will give slightly different results for each. Ballyvoyle is the older name and Ballyvoile is the newer name used in postal addresses.
Ballyvoile Cove Bridge – date on keystone (south side)? Looks like 1822 but slightly damaged. Need to check to see if North side keystone has date?
