Looking for Treaty Annuity (An.) Identification Numbers

Looking for treaty annuity identification numbers for Dakota native Americans.  These are listed on certain Census Records at Pine Ridge and Cheyenne River and Standing Rock, along with the Land Allotment Numbers.  Thank you!

For Example, in 1934 under James McGregor Census at Pine Ridge, the numbers are listed in the last column of the census, along with land Allotment Numbers and U- numbers.  I would like to know if there is a searchable database or if there is a list that can be found on microfiche.  Thanks.
