Calvin L Nuckolls might be my GGG Grandfather. Story goes he came west from Grayson VA with 3 brothers, they made it to a bar in MO and had a fight, one brother S.F (could be wrong here) got mad at them and said he disowned them and left MO for the west coast. He changed his last name to Nuckols. He was born in 1831 un VA and died in 1881 in Tarkio MO. He was Married 1858 to Anna Lewis in Hamburg IA. She was from Dayton OH. They had 10 children.
I would like to share any more info you might have on him.
