Looking for James Henry Keen from Kentucky OR Tennessee

My Grandfather, JAMES HENRY KEEN married MAUDIE ROW about 1902. They were in Bryan County Oklahoma by 1910. JAMES HENRY KEEN (J.H.) died between Valient & Wright City, Oklahoma about April 27th 1933. He was survived by Maudie, sons J.T.(Johnnie Thomas), W.I.(Wilburn Isaac), Clarence Delbert & daughter Maggie Elizabeth(Lizzie) Pruitt. I think he was born in Kentucky (Maudie was from there) or Tennessee. Any information on him would be helpful. This is all I know about him. He was a farmer. Thanks.
