Laura, Can you give me a little more information? I didn't find them listed in my marriage book, but I do have several other books I can check. Anderson was not created until 1827 from Franklin, Mercer and Washington co. Did you find them on a census in Anderson co? All the above cos. were created before 1800 so it help you to try and narrow it down. I have found this name spelled Guin, Gwin, Gwinn, Gwyn.
