Harry "Doc" Sage was the regular catcher for the Toledo Maumees in 1890. He also played at least 12 seasons in the minors. He managed several times in the minors for his hometown team of Rock Island, and in 1905 he wrote about his memories of baseball for the hometown Argus newspaper.
The Sporting Life issue of April 28, 1900 mentioned that Harry's nephew was a minor league umpire and had previously played with some teams in Omaha, but the publication did not say if the teams were professional or amateur, and did not give a name to the nephew other than "Sage". Harry himself umpired one game in the American Association in 1890.
"The base ball events of the past week have been the signing of two first-class players. The first being none other than Harry Sage, of Toledo and Des Moines fame. To comment on this player is unnecessary; his reputation was established three years ago. Sage wanted to go into business in Rock Island, our sister city, and that accounts for our being able to secure him." - Sporting Life's correspondent from Davenport, IA, May 2, 1891
"Manager Harry Sage has seven left-handed hitters on his Rock Island team." - Sporting Life of May 27, 1899
