The South Carolina Department of Archives and History (SCDAH) has a wonderful website. Link here to search their databases.
Among the treasures to be found are images of many wills (1782 to c. 1855) transcribed by the Civil Works Administration (CWA) and the Works Progress Administration (WPA) in the 1930s. Land plat images are available, too.
I'm delighted to have permission from SCDAH to post their images here! Here is a link to Samuel Reed's will.
Check out SCDAH if you haven't already. It's a gold mine!
While you are there, search on Malcom Clark, too. As most of you know, Malcom Clark was Mary Clark Reed's father. He was a surveyor. You not only find images of plats for Malcom's own land, but dozens of plats surveyed and signed by him. Note that he signed his name "Malcom" instead of "Malcolm" as you usually see online. Also, when you're looking, be sure to use every variation of "Malcom" and "Clark" that you can think of, including Malcomb, Malcome, Clarke, Clerk, etc.
Please share with us in the comments the treasures you find!
