Like I said, find the Grand Prairie Historical Society as they can probably fill in a lot of gaps. All of that stuff was going on when I was around Stuttgart in the late 50's to early 60's, I would say.
Dr. Glenn was the first president of the historical group and a mover and shaker in his time. His secretary- the one who typed a lot of that stuff on one of those old typewriters-was the mother of one of my high school friends and she may still be alive at Stuttgart. I know she was until about five years ago.
Good luck with your search.
