||A Vermont militia general, politician, and writer famous for helping to found the state of Vermont, and for capturing Fort Ticonderoga during the American Revolutionary War. His brother Ira Allen, founder of the University of Vermont, also presumably carried I2. A direct descendant of his brother Hemen and other descendants of his immigrant ancestor have tested as the I2-M223 outlier clade I2-Y6099 at the Allan/Allen/Allin Project.
||The President of the Second Bank of the United States. Coming from the prominent Biddle family, some of his relatives also likely to have carried I2 include millionaire Anthony Joseph Drexel Biddle, General John Biddle, and cinematographer John Biddle. His family has tested at BiddleEtc.
||I2-M223-Cont2a Z76+ CTS6433+
||An American frontiersman, folk hero, and congressman from Tennessee. The Crockett Families DNA Project has tested his family, including a direct descendant of his father John Crockett.
||Regent of Hungary through most of World War II. A cousin of his has tested, per Vadim Verenich and others at MolGen (in Russian).
||I2-M223-Cont Z76+ L1317+
||The 17th President of the United Sates, who had been Abraham Lincoln's 2nd Vice President until Lincoln's assassination. The Johnson/Johnston/Johnstone DNA Surname Project has him listed as I2, and the I-M223 Project has his family's haplogroup categorized.
||Taoiseach of Ireland and leader of Fine Gael. He tested personally in 2013, and Spencer Wells further clarified that his subclade is I2-M223 CTS616+ at the Genetic Genealogy Ireland 2014 Conference, although he hasn't yet been specified more.
||A Louisiana politician famous for his left-wing populism and his motto, "Every Man a King," who was assassinated in 1935. His family has tested at the Long Surname DNA Project.
||The most famous Protestant reformer. Several suspected relatives, including one genealogically traceable 1st cousin 13 times removed, have tested as I2a-Din-N at the Luther Surname DNA Project and on ySearch (see especially ySearch ID: YTE6E).
||Governor of Wyoming. He, as well as his distant relative, Vermont Governor John A. Mead, have relatives who tested and matched at the Mead Surname DNA Project.
||A Serbian vojvoda noted for his military successes in World War I and other wars. Sinisa Jerkovic at Poreklo (in Serbian) provides the haplotype of his cousins, as well as an argument in favor of his relationship to the Božović family and his descent from a 15th century Serbian warrior named Captain Gojko.
||I2-M223-Cont2 Z76+ CTS6433+
||The first President of France and its last monarch, who held the title Emperor of the French. Although legally the nephew and heir of Napoleon Bonaparte, both descendant testing and direct testing by researcher Gerard Lucotte have proven the two to be unrelated paternally. The STRs of a descendant are predicted to be I2-M223.
||A Mayflower passenger, signer of the Mayflower Compact, and military leader for the Plymouth Colony. The Mayflower DNA Project has tested descendants of his.
||I2c L596+ PF3827+
||The Prime Minister of the Democratic Republic of Georgia through most of its existence, as well as the head of the DRG's government in exile from 1921 to 1953. A descendant tested as I2c. This sample is available at ySearch ID: DUPCV.
