I am looking for my grandfather Calvin Marion Tecumseh coker born 1/1/1881 in denton,Texas. His father, my greatgrandfather Hansford coker and greatgrandmother virginia pauline davis. Virginia was suppose to have been on the trail of tears. We do know her people were relocated and given land in oklahoma. My grandfather calvin's name was missed spelled on his marriage certificate as calvin caker, he married addie lee sampson 10/24/1903. On the dawes rolls there is a calvin that would have been the same age as calvin. I have hit a road block any help would be so appreciated.
