John Arlin Floyd, we probably are related, but you might be surprised as we have a number of Black relatives according to DNA. I cannot tell anything from your tree as you only have your parents so just posting something here is not much help.
If you add more to your tree, I am happy to assist connecting your great great grandfather to the correct Floyd in Horry. I know of several lines that went to Georgia.
John Arlin Floyd, I have researched most all Floyd lines in Horry, Georgetown, and Marion Counties, SC along with Robeson and Columbus Counties, NC. They are all related, but it is important to know the correct line as you are probably back circa pre Civil War with your gggrand father. .
