Re: 1st Mounted Rifles
Thomas J. Spicer did enlist in the 1st AR Mtd Rifles but immediately took ill and was discharged six weeks later, deemed unfit for duty. In 1891, he applied for a pension which shows he was in both the 1st AR Mtd Rifles and the 3rd MO Cavalry though I didn't find a service record for him in the 3rd MO Cav.
