W. G. Ryan line 7 40 Farmer born Tennessee, November 30, 1863. As the Civil War dragged toward its third year, President Lincoln signed the Enrollment Act in March 1863 to supply more troops to the Union army. The law subjected men ages 20-45 to a draft. Enrollment began shortly thereafter, with men's names recorded on consolidated lists from which draftees would be selected. In the end, bounties for enlistment offered by federal, state, and local governments ensured that most Union troops were volunteers. U.S., Civil War Draft Registrations Records, 1863-1865.
