I think a couple of Joe Choynski's fights are missing.
According to the Boxing Register, he fought George Bush on November 14, 1888, in San Francisco. Choynski won by a second round knockout.
Also, the Boxing Register has him fighting James J. Corbett three times in 1889, not just two. They have Corbett winning a four-round decision on July 15, 1889 in San Francisco.
