From what i can tell there are three major groups of demby's. One is African American ( My father told me that freed black slaves were know to take on there masters last name, but that might not be right). Another is the Constance Demby group. My father meet Constance Demby when he lived in California and told me that she was either not related or very distantly related. Then there is my group who from what i have gathered from my uncle and father(before i read your article) were welsh and came to america via either virginia or south carolina. They then stayed for a while in the georgia south carolina area. Then went west to Arkansas. There some of them maried indian(Pick a Cherry is the one i have been told of) But somewhere in this time James W. Demby(the old) one apeared. I always thought he was born and raised in Arkansas. James W. Demby was one of the major players in a group That went north and i think made up the first Arkansas Union calvery(the point is he fought for the north). His fighting for the north made things hard on his family during the war, but afterward he became a well known man in Little rock and was editor of The Arkansas democrate( I am not shure about that)but he then or before i cannot tell you was put in charge of the Arkansas militia (this part i can back up. I can verify this becouse i have seen the newspaper article)Then while he was in charge of the milita the KKK in Arkansas had i big uprising. They had taken controle of a good deal of southern arkansas and killed a few people. James W. Demby then took the Arkansas militia down and after a breif skirmish beaet down the revolt and proptly hanged the leaders of the uprising. The article said that the governor or someone important had said that at the rate the revolt was growing there would not have been a force big enough to stop them withen the state.
