He was the son of William Dickie. Dickie married Eleanor Chapman around 1812. He was lieutenant colonel in the county militia and a justice of the peace and served as justice in the Inferior Court of Common Pleas. He died at Goose River, Cumberland County, Nova Scotia, at the age of 69.
His son Robert Barry Dickie served in the Canadian Senate and is considered to be one of the Fathers of Confederation.
