President William McKinley is my 12th cousin 7x removed. The ancestor who connects us together is Princess Mary Stewart (1380 – 1382), my 18th great grandmother.

William McKinley Jr. (January 29, 1843 – September 14, 1901) was the 25th president regarding the United States, serving from March 4, 1897, until his assassination half a year into his second term. During his presidency, McKinley led the nation to victory within the Spanish–American War, raised protective tariffs to market American industry and kept the world from the gold standard in a rejection of free silver (effectively, expansionary monetary policy).
