William Fraser (bishop of Arichat)
William Fraser was a Canadian Roman Catholic priest and the first Bishop of Halifax in Nova Scotia from 1842 to July 20, 1845. He was Bishop of Arichat from September 22, 1844. The difference in the dates is due to the splitting of the diocese into two dioceses effective September 22, 1844, and Fraser remaining Bishop of Halifax until such time that William Walsh took formal possession of the diocese of Halifax.
