help.. need info on Gracie Edith Demarcus....

I am new at the geneology site and I seen how much every one is helping maybe this problem can get fixed! My g.grandmother Gracie e. demarcus was born 11-9-1912 and died 2-4-1994. She was married to a Rev. Roy T. McCoy. All I know is that they were living in either Fonde, ky or tenn. in the 1900's. They had 5 kids. I can not seem to get past that! Thanks for the help!
