Migration
Early migration routes to and from for emigrant settlers included:


 * California Trail 1846 to 1869 from western Missouri to northern California
 * Applegate Trail since 1846 (avoided the Forty Mile Desert) by leaving the Humboldt River in Nevada early at present-day Rye Reservoir, Nevada and passing through the Black Rock Desert to Fandango Pass past Goose Lake on to the Lost River and eventually the Willamette Valley in Oregon
 * The Lassen Cutoff 1848 was established by gold rushers from Oregon going to California. It branched off the Applegate Trail at Davis Creek, went through Devil's Garden to the Pit River passing east of Mt. Lassen, and turning west to Lassen Rancho, California, and from there to Sacramento. In some years as much as 1/3 of emigrants mistakenly took the Applegate Trail-Lassen Cutoff, a much longer and more difficult trail than the Truckee or Carson routes.

Voting Registers
California county clerks were to keep voting registers every other year from 1866 and well into the 20th century. These large books, called Great Registers, listed the men who registered to vote in that county. Besides name and age, the record may show place of birth, address, occupation, naturalization date and sometimes even a physical description.

These records are at the California State Library (1866-1944), and microfilmed copies are available through Family History Centers (1866-1910). Ancestry ($) has a searchable database of Modoc Great Registers from 1875-1898.
