Stotler glass plate negative

This is an attempt at scanning a dry glass plate negative with my flatbed scanner then reversing the image and tweaking it with photo editing software.

I am not 100% certain who this image depicts. The box is labeled "Stotler" and there are no dates on it. My assumption is that it is a photo of Hiram Stotler (1838-1920). I have another photo labeled Hiram Stotler, but it is a much older man, so I'm not sure if they are the same men. I'll update this post in the future if find a name in one of the boxes of photos that I haven't searched yet.

Update: I found this same picture in a photo album labeled John Henry Stotler on the reverse, but George Henry Stotler underneath it. A similar picture is labeled Henry Stotler. The 1870 and 1880 Census both list George Stotler as the oldest son. Whatever the correct name is, it is clear that this is a brother of Mary H. (Stotler) Ross.

There is a second box of glass plates with 3 plates also labeled Stotler. One image is of a large tombstone labeled Stotler with the "Woodmen of the World" logo on it. The logo also says "Dum Tacet Clamat" which apparently means, "Though Silent He Speaks." The second image is the same tombstone with a woman standing next to it. The third image looks like men standing in a river or lake, possibly an immersion baptism?

Update: I found the same photo in an album labeled Aunt Emma at Henry's grave - 1902 Crown Hill cemetery - Indianapolis, IN. So it would appear that Emma was the wife of George Henry Stotler.

The Stotler connection to the Brassfield surname is Hiram Stotler (1838-1920), father of Mary Hay Stotler (1864-1959) (married John Franklin Ross (1859-1934)), mother of Clara Bernice Ross (1897-1994) (married Frank Brown Fowlie (1892-1977)). Frank and Clara's daughter married Elvis John Brassfield (1920-2006).
