1. Mary Tyler (1815–1847)

3. John Tyler, Jr. (1819–1896)
4. Letitia Tyler Semple (1821–1907)
5. Elizabeth Tyler (1823–1850)
6. Anne Contesse Tyler (1825-1825)
7. Alice Tyler (1827–1854)
8. Tazewell Tyler (1830–1874)
Tyler’s second wife was Julia Gardiner Tyler (July 23, 1820 – July 10, 1889), with whom he had seven children:
1. David Gardiner Tyler (1846–1927)
2. John Alexander Tyler (1848–1883)
3. Julia Gardiner Tyler Spencer (1849–1871)
4. Lachlan Tyler (1851–1902)
5. Lyon Gardiner Tyler (1853–1935)
6. Robert Fitzwalter Tyler (1856–1927)

As of 2012, two of Tyler’s grandchildren were still alive: Lyon Gardiner Tyler, Jr. (b.1924), and Harrison Ruffin Tyler (b. 1928). Harrison Tyler maintains the family home, "Sherwood Forest” which John Tyler acquired in 1842. Purported at 300 feet to be the longest frame house in the United States, Sherwood Forest sits on a James River plantation, near Charles City, VA.
