Kevin CummingsPasted below is a box score from a game between The Philadelphia Quakers and the Philadelphia Athletics from The Sporting News of Saturday, April 16, 1887.
As you can see, Gus Wehing's name is in the box score. I am guessing that the poor quality of the image is preventing the search tool from finding it. Even when I am on the page itself, a search does not turn up the reference. I am also guessing that the success with your searches is related to better conditioned images from the period during which your cousins played.
Not that this was totally unrewarding. Since Weying's name is associated with the Philadelphia National League team, it would seem to prove that the reference above was not a fluke and that he did, indeed, play for the Quakers, a fact unreported in any of his historical data of which I am aware!
