Edward Readie "Reed" Brigham" Young
Born Feb. 15, 1867, Kellyton, Coosa County, Alabama
Died Mar. 20, 1940, Duncan, Stephens County Oklahoma
Second sheriff of Stephens County OK. A three-page obit appeared in the Duncan paper when he died. They come from a family of 12 children and their grandfather is pretty famous back in Tallapoosa Co. AL. He was Bird H Young and a writer in the mid 1800's made him famous by writing semi fictional and most true stories about him. The book is called "Adventures of Simon Suggs, Late of the Tallapoosa Volunteers; Together with "Taking the Census" and other Alabama Sketches" by Johnson Jones Hooper.
No cavalry companies from Coosa County served in any of Wheeler's Alabama commands.
The "Coosa Cavalry" was an Alabama Volunteer Corps company which never entered Confederate service. Details available if anyone wishes.
Page 24 of Wyeth's "That Devil Forrest" lists the four Alabama companies in N. B. Forrest's original command. These came from Marshall, Madison, Cherokee (not Etowah) and Wilcox (the south Alabama company). Wyeth makes a mistake on page 26 by ascribing the "McDonald Dragoons" to Alabama. Capt. Charles McDonald and his company came from Memphis, Tennessee.
An Alabama company called the "North Alabama Cavaliers" joined Forrest during the winter of 1861-62. Officers and men came from Madison County, AL. This company surrendered at Fort Donelson and never served under Forrest again.
If you check the Alabama message board, I found a Captain McDonald who qualifies as an Alabama officer leading mounted men who *might* have been from Coosa County. McDonald received a parole as Captain of Supporting Forces, 6th Congressional District. Coosa belongs in the 3rd Congressional District of Alabama, but men from other areas could have joined.
And that's all I know about that.
