Hi Mary !
Dang. I remember reading that plaque and didn't take a picture of it. :] You might look at this web page - http://iagenweb.org/chickasaw/churchlittlebrown.htm
and then on that page towards the top is a link to the church page. If you don't find what you are looking for there, if I remember right there are ways to contact the people there. Best of luck.
