Jessie Harlan Lincoln (November 6, 1875 – January 4, 1948) was one of the three children of Robert Todd Lincoln and a granddaughter of Abraham Lincoln. Jessie and her sister Mary "Mamie" were the two children of Robert Lincoln to produce children. In 1897 Jessie married Warren Beckwith and produced two children:
- Mary Lincoln Beckwith "Peggy" was born on August 22, 1898 and died unmarried in 1975.
- Robert Todd Lincoln Beckwith was born on July 19, 1904 and died December 24, 1985. He married Hazel Holland Wilson, Annamarie Hoffman and Margaret Fristoe. None of these marriages resulted in children. He was therefore President Lincoln's last direct descendant.
Jessie's later marriages with Frank Edward Johnson and Robert J. Randolf did not result in any children. Jessie's sister and brother were respectively:
- Mary "Mamie" Lincoln, October 15, 1869 – November 21, 1938
- Abraham "Jack" Lincoln II, August 14, 1873 – March 5, 1890
