Booth's "Records" contains only a final parole record for Private Samuel Whitehurst, Company B, 8th Louisiana Cavalry regiment. As required under the terms of the surrender of the Trans-Mississippi Department, Samuel reported into the Federal parole center at Shreveport, Louisiana to give and receive his final parole on June 15, 1865. He stated that his place of residence was Bossier Parish.

Dr. Bergeron's "Guide to Louisiana Confederate Military Units 1861-1865" (LSU Press, 1989) presents a brief history of this late war cavalry unit. Dr. Bergeron's "Guide" does not identify Company B with any particular parish.

My first pass guess from this end-of-war service record is that Samuel Whitehurst was a young man between 16 and 18 years of age who had been enrolled in state militia service sometime before 1864. With the final modification of the Conscription Act in February 1864 to require enrolled Confederate service of white male residents ages 17 to 50 years, the Louisiana State Militia was dissolved and its units transferred into Confederate service. Surviving Confederate military records for this second half of the war don't usually tell you much more than this.

My personal experience comparing Booth's "Records" with the Compiled Military Service Records on microfilm at the National Archives is that Booth's archivists sometimes left out tidbits of information that might be helpful to genealogy researchers. In this case, I would not expect it, but you should check the CMSR. The State Archives in Baton Rouge also have these microfilmed CMSR records.
