Families of deceased Civil War soldiers (Colored Infantry) who applied for Bounties and/or pay allowances.

I received the pension files for two of my ancestors who served (and died) in the Civil War (U.S. Colored Infantry in Missouri). They each include references to a “bounty” that was paid to their family members, possibly for back pay or other allowances that were owed to the soldiers.

One of the documents has a sort of receipt with a certificate number. But the only reference to where it came from is Treasury Department, Second Auditors Office.

The other contains is a declaration made by the solder’s sisters that was certified by the local court.

I’d like to find all records of these payments, including the original applications, but I don’t know where to look. They are not with the rest of the pension files of the soldiers.

I appreciate any help you can provide.
