I've searched a bit more, and I think there were TWO Nelson Shoults in MO during that time.My Nelson eventually went to Texas, where he is found on the Texas census:
From 1860 census, Fayette, Texas, page 135 Plum Grove, Texas at house 1007 (image 119 of 182)
"Nelson Shoults, age 21, laborer, born Missouri; Clarissa Shoults, age 18, born Missouri; Matilda W shoults, age 5 months, born Texas"
Further down the census sheets at house 1000 are:
"Jacobs Shoults, age 50, farmser, born Kentucky; Rachel Shoults, age 50, born Missouri" (they obviously are the same Jacob and Rachel shown in 1850 in Missouri, but just haven't aged as much as expected!)
"Shoults Narcissus 157 Jefferson County
Narcissus Shoults and Miss Clarissa Offutt both of Jefferson Co., Mo.; married on 28 April 1859 by Alfred Stewart, JP at Jefferson Co., Mo.; the hand written index has Clarissa Offut
from http://vienici.com/moabs/last.asphttp://vienici.com/moabs/last.asp = transcribed Marriage licenses from Jefferson County, Missouri.
Was Nelson's name really Narcissus and his common name Nelson? Or has it been transcribed incorrectly? MKY
In any case, here is the Death and marriage information taken from a Texas Widow's pension application by Clarissa Shoults in 1906:
War Department file 1115263Washington, March 30, 1906Letter to the Comptroller, State of TExas, Austin."The records of this office show that Nelson Shoults, also borne as Nelson Shultz, private, Company I, 16th Texas Infantry, C.S.A., was enlisted April 3, 1862, at Camp Terry, to serve during the war.On the roll of the company for the months of January and February, 1864, last roll on file, he is reported "absent of daily duty." No later record of him found.Signed F A (unledgible)
Sworn statements by Ed Smith and C.B. Hall, both having served with Nelson Shoults in the confederate armies, state that they were in the same company with the said Nelson Shoults "and he did not desert the Confederacy".Sworn 12 February 1906
So, I think this is my Nelson and Clarissa.
