John Quincy Adams (July 11, 1767 - February 23, 1848) was a diplomat, politician, and the sixth President of the United States (March 4, 1825 – March 4, 1829). His party affiliations were Federalist, Democratic-Republican, National Republican, and later Anti-Masonic and Whig. Adams was the son of United States President John Adams and Abigail Adams. He is most famous as a diplomat involved in many international negotiations, and for formulating the Monroe Doctrine. As president he proposed a grand program of modernization and educational advancement, but was unable to get it through Congress. Late in life, as a Congressman, he was a leading opponent of the Slave Power, arguing that if a civil war ever broke out the president could abolish slavery by using his war powers, a policy followed by Abraham Lincoln in the Emancipation Proclamation of 1863.

John Quincy Adams II (September 22, 1833 – August 14, 1894) was an American lawyer and politician, the grandson of president John Quincy Adams, and the son of Charles Francis Adams.

Adams graduated from Harvard University in 1853, practiced law, and then established an experimental model farm near Quincy, Massachusetts. He married Frances (Fanny) Cadwalader Crowninshield, daughter of George and Harriet Sears Crowninshield of the politically powerful Crowninshield family.

Adams was elected to the Massachusetts state legislature in 1866 as a Republican, but soon switched to the Democratic Party because of his disaffection with president Andrew Johnson's Reconstruction policies. He was nominated for Governor of Massachusetts in 1868, 1869, and 1870, but was never elected.
