From California Historical Landmarks:
Lotta Crabtree was born in New York in 1847. In 1852-3 the gold fever brought her family to California. Several months after arriving in San Francisco, Mrs. Crabtree and Lotta went to Grass Valley and with Mr. Crabtree started a boarding house for miners. It was here that Lotta met Lola Montez, who taught her to sing and dance. In Scales, Plumas County, Lotta made her first public appearance, which led to a successful career on stage here and abroad.
