Yes, I have come across 'Alphonso' many times in my research, but believe him to be a different person than the one I am researching, Alonzo James Ellis.
According to census records from 1850/1860, Alphonso was 9 in 1850 and Alonzo was 22 in 1860, making them three years apart in age.
Also, Alonzo's service records have him in the 5th Regiment, Co F at the time that Alphonso is listed in the 7th.
It gets worse..Alonzo had a sister named Alphonsa.

Thank you for your assistance.
