(c. 1910s-c. 1930s)
Independent (c. 1910s–19,21–25,27–c. 30s)
The Dayton Marcos history predates the formal organized leagues of Negro league baseball. As an independent team, and also in the Ohio-Indiana League, they played black and white teams all over the country throughout the 1910s.
Old newspaper accounts and fading memories are the only sources of information on the Marcos. They played in the then newly formed Negro National League, which was formed by Rube Foster. The Marcos were one of the original eight teams to play in the first organized major Negro league to survive a full season.
Negro National League Years
Dayton left the league after one year and a last place finish, and played independently until the mid-1920s. They then rejoined briefly for part of 1926, when they finished in second-to-last and left the league once again.
