thats a hard one because your asking about records and who kept them .
Because Wyoming was a territory not a state , your probably going to have to go through the US government . Thus the library of congress.
You may be able to trace the number through the Museum of the American Indian.
You might find information from the state of Wyoming itself . But most like it the federal government who would have that . The other issue you may run into is that there may in fact be no name associated with the tag . Possibly only a people .
If it’s a reservation tag then you probably will have a name associated with it .
Date of death , Secom stance of death and place of death
But out side the Rez system , if the person was not a notable person , then frankly , the government didn’t care . It then will again most likely only have a suspected People , place of collection and circumstance of death.
Now if you do get lucky and the number does have a name associated with it . Then you into a whole nother issue . The reason is that the name may end up being a report name .
The reason this becomes an issue is that a lot of times , because the government officials could not , nor did not want to take the time to figure out how to spell a persons true name in English , they would list a new name .
So lets say your name was Tiotanegi . The government officials would often just say .; from hence forth your John Smith ..
Never mind no one ever called you John Smith . Nor did you ever use that name but to receive rations .
So now you have to start looking through reservation listings OR through later Lists like the Dawes reports , which were drawn up during a time where there was alittle more concern with getting things right .
Even then a lot of times people end up having to go through religious documents from the different churchs , so as to find out who was really who .. The reason for that is that unlike the government , some ,,,,â€some†of these groups actually took very good records of their congregations and listed both the report name and their peoples TRUE name .
So lets say you get that far . Now you will have to figure out who , if any immediate family may still survive. The case may simply be that there isn’t anyone because during this time whole families were annihilated .
So IMO if you truly feel that you want to return this item . The best thing to do is try and find out what people the person belonged to .
From there you then contact that peoples Reservation and ask how to proceed with its return . They will then have the resources to insure that the item is either returned to the rightful relatives OR dispose of the item as their specific belief entail
