Al Kellogg played in 1908. He managed one hit in eight at-bats. Unlike anyone I've talked to in about 35 years, he was able to admit to being around during the Cubs last World Series win.
Bill Kellogg played during the 1914 season. He managed to get 21 more hits than Al, but his batting average was about .175. He was probably cheering for those 1908 Cubs.
Nate Kellogg played in 1885, so some statistical data is lacking. It looks like he played in 5 games during 1885. He also witnessed a stretch of years where the Cubs were one of the best teams in baseball. The Cubs were N.L. champions in 1876, 1880, 1882, 1885, 1886.
