Cooper Family from Nowata County, OK

I am looking for anyone who may be related to this line of Cooper's that came to Nowata Co., OK around 1900 or so. James Cooper (1863-1944) wife Iza R. McMillan Cooper (1866-1943). They had the following children:

Charles Wm. Cooper (1886-1974)
Samuel Newton Cooper (1888-?)
Earl Stockton Cooper (1890-1891)
Roy Eldon Cooper ( 1892-1976)
Hattie Marie Cooper (1898-1975)
James Ernest Cooper (1900-1978)
Cary Thomas Cooper (1904-1985)
Lloyd Franklin Cooper (1906-1907)

Some of these children are buried in Mt. Washington Cemetery there in Nowata Co. I am wanting here from anyone who may know this line or be realated to it. Thanks!
