Dozens of documents from Abraham Lincoln's family are being donated to the Abraham Lincoln Presidential Library and Museum in Springfield.
The 77 documents include items from Lincoln's son and daughter-in-law, along with a letter from Patrick Henry that was written in 1786.
The papers were donated to the museum by the family of a man who spent 30 years working as the curator of the state's Lincoln collection.
Museum officials say the donation shines a light on the personal lives of Lincoln's family.
The stash includes personal notes from the wife of Herbert Hoover to Lincoln's daughter-in-law, Mary Harlan Lincoln.
The material focuses in part on how Robert Lincoln helped members of his mother's family and how Lincoln descendants spent time at Robert Lincoln's Vermont home in the 20th century.
