I have copies of the GREAT REGISTER (which is what they call the voter registration list) for Inyo County, CA for the following years: 1866, 1871-72, 1908

I am happy do to look ups, or you can call the Inyo County Recorder's office at the Courthouse in Independence, to order your own copies for about 15 cents per page. They are very nice people to deal with and their phone number is:
760-878-0410
NOTE: They are open M-F during regular business hours, but closed daily for lunch between 12-1 pm
