It seems that the state of Ohio has the most miles of "track", the most "stations", and even the most "conductors" on the Underground Railroad. So, to make searching easier, I created a category just for Ohio. It simply Category: Underground Railroad, Ohio : https://www.wikitree.com/wiki/Category:Underground_Railroad%2C_Ohio
So, if you run across a person who was a part of the Underground Railroad in Ohio, you now have a new place to put him/her. Thanks so much!
