W. J. H. Traynor

William James Henry Traynor (born July 4, 1845 in Brantford, Ontario) was a Canadian-American anti-Catholic political activist. He is best known for heading the American Protective Association, a nationalist and anti-Catholic organization.

He moved to Detroit, where he was editor of the anti-Catholic weekly, The Patriotic American, and was elected Supreme Grand Master of the Loyal Orange Institution of the United States.

Traynor was elected Supreme President of the American Protective Association in 1893, and he continued to head that organization during its peak of influence in the middle 1890s. He continued to lead that organization until APA founder Henry F. Bowers was returned as the group's leader in 1903.
