[or-roots] agent lists

[Diane]

Is there a list of the Indian Agents, or what ever their title was called, 
for the 1880's to the 1910's?

I am searching for more on Frank Matthews, who married Ida Spittler in 
Indian Valley, Idaho in 1887. She left him  in Fort Bidwell, California 
before 1890.  Family stories say she found out when they were at Fort 
Bidwell he already had a wife.

Just wondering if he had anything to do with Indian affairs in any way. 
Hence the reason they lived at Fort Bidwell.
