From an article about the Marett family reunion at Beaverdam Baptist Church, Fairplay, SC
Article from August 17, 1915 (Volume 7 Number 5) ed. of the Tugaloo Tribune, Westminster S. C. (Contributed by Sheila Casper and Karen Mulder)
Paragraph 6 ...and then Mr. Elias Jackson Marett, of Mississippi was introduced. He spoke one hour and a half, telling of the recollections of the Fair Play neighborhood and its people who lived there sixty years ago. Rising to speak, Mr. Marett said it was one of the most pleasurable moments of his life to stand in Beaverdam church and speak on such an occasion. He was thrilled with joy and happiness to be permitted to speak at the place he regarded as sacred ground after such a long absence. Mr. Marett is 81 years old. In 1852--63 years ago--he left Fair Play with his father, Benjamin Marett, and moved to Texas. Later he settled in Tipper [Tippah] county, Miss., where he has been surveying and practicing law. At the time he lived in Fair Play he knew all the settlers for miles around and he named them all and their children in his speech Friday. Our townsman, Mr. S. H. Marett, is the only living person who was living in the neighborhood then. The speaker had Squire to sit near him to vouch for what he said. Among the names of the first settlers of Fair Play, as told by Mr. Marett, we mention a few: Hollands, Striblings, Maxwells, Moss, Isbels, Simpsons, Jollys, Maretts, McCants, Harbins, [?Coles?], Reeders, Messers, Bartons, Shelors, etc., etc. The speaker named the early teachers and preachers of the vicinity-It did not take so long for a person to become a teacher then as it does now. He said the first school he attended at Beaverdam was taught by a man named Williams. Mr. Marett is well informed, and his speech was listened to with rapt attention, not only by the members of the family, but by the visitors as well.

My several years of research has located numerous unpublished sources and the information garnered is for publication on the 32nd & 45th Miss. regimental histories and the Wood's-Lowrey brigades, after I found and purchased the 32nd & 45th Miss. (Consolidated) previously unknown regimental banner in Wichita, Kansas in June 2002. The consolidated regiment's flag was originally issued around early March 1864 while they were in winter quarters near Dalton, Georgia.
Hope you find this a helpful and informative response to your posting on MSCWMB.
Best regards.
