Buried at Avery Cemetery in Lincoln County is an Ellen Thompson. I do not have the dates on the tombstone. Next to her is a sunken area that looks to be an unmarked grave. I believe that this is where Marion Tompson, her husband is buried.
From the 1910 Census Lincoln Co. Pawnee twp. 204-211, Marion Thompson was age 71 born IN, his parents both born in NY, he was a veteran of the Union Army (Civil War) and wife was Ellen.
He is no relation of mine, but I am trying to locate graves of all Civil War vets buried in Oklahoma.
