I think you are looking at a warent that is like a deed warent for land ,other warents are like when the British or Tores put a warrent on you head because you were for the U.S.A to be free from King George . the letter D must mean like a deed warent to the creek so that you own the land and water way for your crop,s . Hope you can understand the word warrent .If not you might try a Layer and see if it is a court patment warrent from the two people. think of you being a jury and getingt paid with land that is just 0.25a acer and tobbacco is your gold in that time.
