3 points to help with dates
1) At one time, my banker in Atlanta had the surname Beall. She complained that no one spelled it correctly. Of course, she also pronounced is identically with the word "Bell." So you'd always need to consider alternate spellings.
2) There is great documentation for Justiana at the site:

http://www.gabartow.org/Cem/cem.OakHill_06.shtml3) If you search within Google in their Books search, you can use the terms "Justianna D. Hooper" "1801" to get a snippet view of the book "Biographical and historical memoirs of Mississippi:
embracing an authentic and comprehensive account of the chief events in the history of the state and a record of the lives of many of the most worthy and illustrious families and individuals, Volume 1": Reprint Co., 1978
page 364, which also includes documentation of the birth date for Justianna D. Hooper and which gives her birth location as Anderson District, SC.
Finally, I'm a Hooper researcher, so can't help too much with the Bealls, except to add that Noble and Justianna were the maternal grandparents of Asa Candler, who in Georgia is EXTREMELY well known as the man who made Coca-Cola famous. Although I've only seen a review, I would imagine there might be quite good documentation, and perhaps endnotes with guidance for more resources, in the book
"Kathryn W. Kemp, God's Capitalist: Asa Candler of Coca-Cola. Macon: Mercer University Press, 2002." The book has nearly 300 pages of biography and is based on the author's research into Coca-Cola company archives and the Candler papers at Emory University.
