Saturday afternoon I spent a few minutes at the TN State Archives browsing their collection of Nashville City Directories. I see in the 1907 Directory that Charles E. W. Dorris has moved to Los Angeles, California.
In 1906 he lived in West Nashville on Morrow Road near Kentucky Avenue; in 1908 he is back in the same block of Morrow. And sometime in or during 1907 he is in LA. Preaching I assume, but I can’t verify even that.
