The James Martin I show that belongs to George W. and Mary Martin is James O. Martin born about 1843 married a Margaret Rowden. I am not sure how you could look up census for Oklahoma in 1880 that would have been before the Oklahoma Run for land in 1889. Only 1900 census were taken for the Indian and Oklahoma Terr. Perhaps they went Ark. That is where I show most of my Martin's went from Mo. Esta
