Looking for the cemetery where James B. Douglas(s) is buried.

James was born circa 1829. He is listed on the 1900 census, in Chicot County (he had land/homes in both Chicot County and Drew County). I can't find him on the 1910, 1920, or 1930 census.

I've been told James is buried "in Monticello."

Any help would be greatly appreciated.

Thanks!
Julie
