Uncle Cornelius Richert 84 th Birthday

The photo below is of Uncle Cornelius Richert, Clarence Richert, and Jake Richert. The photo was taken on September 21, 1961.

If anyone knows where this was taken please let me know.

I want to know their relation to my Grandmother Mary Sarah Duerksen Wiebe?

The top photo is the original and the bottom photo is one I restored using Photoshop.
