Dr. Junius Mottley was born in Virginia in 1812 to John P. and Mary Williams Elmore Mottley. His ancestors came to Virginia from England in the 1600s. Dr. Mottley received his medical education at Transylvania University in Lexington, Kentucky. Transylvania was founded in 1780, was the first university in Kentucky and is still operating.

Shortly after leaving Kentucky, Mottley moved to Texas in 1835. He joined the Texas Army and served as Post Surgeon at Goliad. Mottley was serving in that capacity in early 1836 when he was appointed as a delegate to the Constitutional Convention in Washington County. Accordingly, he was a signer of the Texas Declaration of Independence.
