Samuel Lincoln was an Englishman and progenitor of many notable United States political figures, including his 4th-great-grandson, President Abraham Lincoln, Maine governor Enoch Lincoln, and Levi Lincoln Sr. and Levi Lincoln Jr., both of whom served as Massachusetts Representatives, Governor and Lieutenant Governor. Because of Samuel Lincoln's descendants, his fortuitous arrival in the Massachusetts Bay Colony, and the fact that his ancestry is known for several generations, he is considered the father of the most prominent branch of Lincolns in the United States.

Abraham Lincoln was an American lawyer, politician, and statesman, who served as the 16th president of the United States, from 1861 until his assassination in 1865. Lincoln led the United States through the American Civil War, defending the nation as a constitutional union, defeating the insurgent Confederacy, playing a major role in the abolition of slavery, expanding the power of the federal government, and modernizing the U.S. economy.
