I was a Game Warden and road MP on Fort Rucker back in the early '70's, when it was a closed post and all the (then) cemeteries were on the Exclusive Federal Jurisdiction portion of the post.
I became quite fascinated with the history of the post and always searched out more info about some of the families that had been misplaced in the early '40's.
Many people think that the cemeteries were simply abandoned, but that wasn't the case.
The Army went to great lengths to relocate them.
You can go here: http://www.southeastsun.com/daleville/article_b93ddb94-f106-11e5-90d5-9bf8b6423298.html and perhaps you may recognize some of the family names.
It also links to another story with names that you may recognize.
I never heard of a Sweetwater Grave yard...however there was a church close to the impact area with a Baptismal pool that was referred to as "Sweet Water".
There was some discussion back in the '70's as to whether or not it was a black church.
Your post caught my attention because of my fascination with the subject...it continues to this day, although I've not been stationed on Fort Rucker since 1979.
I've sent an email to my sister on this subject, she is the family historian and genealogist. I did the Family DNA, we're R1b's, V's and U5a's.
I'll let you know something more if I learn any more. I didn't recognize any family names from that list.
