California:
How did three California counties- Marin, Solano and Stanislaus – come to be named after three Indian leaders? What was the role of Mariano Vallejo and why did he help establish these names when earlier he commanded the expedition against Estanislao’s rebellion?
One of the sources should be Eye of the Bear: A History of Early California by Naida West, and another source should be Lands of Promise and Despair: Chronicles of Early California, 1535-1846 by Rose Marie Beebe and Robert M. Senkewicz.
You have to use five sources.
