I don't know if this link has ever been provided here.
Try typing the word "slave" in the surname field and over 1600 entries appear. Many slaves are mentioned by first name with additional information such as parents, owners, associations with plantations,churches, comments, etc.
Documents may be obtained for the cost of copying.
The 'curators' at this library/historical center have spent a lot of time extracting and inputting information on Bossier citizens, history, and African Americans in the area.
They are also very, very, helpful and friendly.
