 Little is known about baseball in the 1870s, outside the leagues, but it seems that many clubs such as the Aetnas and their amateur or semipro rivals continued to operate, and thus adult players outside the leagues, such as Hallinan and Quinn before 1875, continued to play competitively.According to one obituary, Hallinan played four season for Aetna beginning 1870.Quinn died, aged 59, from unknown causes in his native Chicago in 1909.
