Omer Weaver was born in 1838 in Arkansas. He was the son of Samuel M. Weaver and Mary Elizabeth Rose Weaver. Samuel Weaver was a prominent businessman and political figure in the state. Originally from Virginia, the elder Weaver settled in the McLean Bottoms of Crawford County in the early 1830s. He and his wife moved to Little Rock in 1836. In 1852, Omer left home to enroll in the Western Military Institute at Drennon Springs, Kentucky. A number of other young men from Little Rock also attended the institution. Following his return to Arkansas, Weaver worked as a clerk in the secretary of state's office. His father was the secretary of state at the time. The outbreak of the Civil War led Weaver to enlist in Woodruff's Arkansas Battery. Weaver was killed in action during the battle of Wilson's Creek on August 10, 1861. He has the distinction of being the first Arkansan killed during the war.
