Samuel Lee and Angeline were the children of Jacob Dillard Mayo and Eliza Gordon. They were born in Virginia but moved to Davidson County, Tennessee withe their parents in the 1830s.
Samuel Lee married Amanda Ezell on 5 February 1848 in Davidson County, Tennessee. They had three children: Zachary Taylor Mayo, William Daniel Mayo, and Amanda Jane Mayo. Samuel Lee married his second wife Tabitha Elizabeth Riggan on 21 September 1854 in Davidson County, Tennessee. They had four children: Samuel Lee Mayo, Mary Mayo, Charles A. Mayo, and Alonzo M. Mayo.
Angeline, her husband Davidson Binkley, and their son William Searcy Binkley moved from Tennessee to Williamson County, Illinois in the 1850s. They had two more children, Anna Malvina (my 2nd-great-grandmother) and James Rutherford Binkley. Davidson enlisted in the Union Army in 1862. He died of measles in Cairo, Alexander County, Illinois while serving with Company G, 128th Illinois Infantry.
After Davidson's death, Angeline and their children returned to Tennessee. In 1870, they lived with her brother Samuel Lee, his wife Tabitha Elizabeth, his son William, and their children Samuel Lee, Mary, Charles, and Alonzo.

By 1880, Angeline and her children lived on their own. Samuel Lee may have helped Angeline purchase a home. According to a note on a family group sheet compiled by P. C. Lampley, Davidson and Angeline (Mayo) Binkley's granddaughter Laura Belle (Tarkington) Leech said that "Lee Mayo" gave "Grandma Binkley" money to buy a house at Vaughn's Gap, Davidson County, Tennessee.

Samuel Lee Mayo seems to have been a supportive big brother to his sister Angeline. She probably felt thankful.
