You may try the Monroe County genealogical society--often, researchers will compile all sorts of information that may not be available on the internet.

Also was Cammon the married name if married or the maiden name?

Regarding the given name; when doing a quick search on Arkansas marriages via www.familysearchlabs.org for Monroe county I see an Edream Lamar married to a P.P. Wilkinson in 1924 and an Edrem Lomax married to an A. J. Wright in 1920.
