I have been researching my MOSS ancestors in Natchitoches Parish. I have been fortunant enough to get tons of information which was submitted by Robert Homer MOSS and Carolyn DOWDEN Grimm. I have information that dates back to John DOWDEN b.Abt 1680 in Maryland. It even includes two DOWDENs that died in the Civil War (Andrew DOWDEN b.1835 in Natchitoches Parish) and (Shelton P. DOWDEN b.1837 in Natchitoches Parish).
The link between MOSS and DOWDEN is:
Enoch MOSS b.10-Dec-1872 in Sabine Parish, married Bertha Leah DOWDEN on 2-Feb-1893 in Kisatchie.
I always heard my grandpa (Wiley Dewey MOSS) mention the DOWDENs, but I didn't know I was related to any.
I would be glad to check any of the family group sheet I have for any information you may be looking for in regards to DOWDEN.
I also intend on placing these family group sheets on my website, which is in desperate need of update. This will take a while.
