Cornelius Ambrosius Logan (May 4, 1806 – February 23, 1853) was an American actor, playwright, and journalist who was father to a famous family of actresses and writers.

He later operated theaters in other cities and traveled with his oldest daughter Eliza, playing comic "yankee" roles.

He also wrote short stories, poetry, notably a well-regarded Ode to the Mississippi, and a defence of the theater against criticism from the pulpit.

Kate (1847-1872) was adopted by politician and Civil War hero John A. Logan, a distant cousin, probably in 1866.

[6] Alice (1844-1917) suffered a mental breakdown on the day of her marriage to actor and writer Albert W. Aiken in 1871; she died many years later in a Norristown, Pennsylvania insane asylum.
