There is a Demond Henard listed on Find-a-grave.com who died in December of 1899. There is also a picture posted.

I have information on a number of Henards in Arkansas as the Henards married into several of my lines and one of the Henard children (now deceased) shared much of his information with me (his mother was an Arkansas Henard).

If you are still seeking info on Demlon (I have him listed as Demmon but I have seen several spelling variants for the same person), please contact me and I would be more than happy to pass on what I know.
