Do you know who We are?

This is a wonderful picture of a church picnic sometime in the late l800s in Lawrence Co.  But I know nothing else about it.  If anyone knows anything about who is in this photo, or when it was taken, or where, I sure would like toknow.  This photo was in the possession of Lena Gray (1874-1965), and we believe she attended this gathering sometime around the time she was married in 1891.  Howard Brooks
