Not sure about the history of the graves. From what I was told by GND, they, and a few more out in the grass, are the graves of people whose families could not be contacted for relocation upon extension of runway 10/28.
Wikipedia has a pair of somewhat-contradictory paragraphs about this, but they both refer to the same reference, which makes no mention of being unable to find "families" - In fact, it quotes several members of the family in the article: https://web.archive.org/web/2003050...avannahnow.com/stories/082801/LOCgraves.shtml
