Chris, I don't think there is a way to find women, seams to me more wer buried with out head stones. I have never found my g-grandmother Louisa Griffith Jone but I know where she is buried in Perry cemetery in a little place, My mother would tell me how her grandfather would go there and paint the little fence around her grave. I can not find her parents Daniel Griffith and Alluzia "Lucy" Prewitt Griffith eithr. The JOnes are so hard to track! MY Jones and tweo brothers James MAdison "Matt" Jones and his brother Martin Jones. Martin was in Ozark, Douglas and Howell co Mo while Madison was in Randolph and Lawrence Co Arkansas. they came from Indiana ! I even have a picture of a Joe Henry Jones on a donkey , when my mother Vergie Collins Morris was young , Joe would come a calling ! Anyway I am thinking that your Margaret did not have a head stone.That she could have been buried on private land. My grandparents are buried in a cemetery called James cemetery , but when I first started looking my mother called it McFann because that who had owned the land , it is in a cow pasture! You have to ask the land owner to go back there . way off the road!
