According to my grandmother born in 1890, her father Michael Gough, was a Gardener to the family living in that building. That was the Strangman family of Strangman's brewery. My grandmother also told me that she was on the grounds of the house with her father when King Edward VII visited Waterford in 1904. Not sure if that piece of lore is true but it's a nice story anyway :-)
Best Wishes,
