F.J. Staton is listed as Lt in Company A 3rd Kentucky Mounted Infantry and as Captain on a cross reference Card in the Confederate Service Records, it says to also reference F.J. "Stayton".
When searching FJ Stayton - he is listed as a LT of Company A - Johnston's Company, 3rd Ky Mtd Infantry. Age 27 years. Mustered in at Camp Boone on (though shows him there in July) Aug 19th, 1861. In looking at his records - there are several - his last name is spelled both Staton and Stayton.
Hope this helps.
