Hi Wikitree family,
It appears he was a confederate civil war veteran. He needs more sourcing showing parental lineage. See his FindAGrave.
Wikipedia: 28th Louisiana Infantry Regiment
Family Search: 28th Regiment, Louisiana Infantry (Confederate)
Wikitree: Category: 29th Regiment, Louisiana Infantry (Thomas'), United States Civil War
Thank you
Note: pension record shows a different date of death? I believe familysearch attached the wrong Ira’s pension. The pension is for a Michigan vet?
Familysearch shows parents as Andrew Mitchell and Phoebe Mitchell
