Louis Trabucco was born in 1821 and emigrated from Italy in 1847. He opened his first store in Bear Valley in 1856. After becoming successful in his Mariposa mining and business ventures he returned to Italy and married 19 year old Elena Lambruschini in 1860. After returning to Bear Valley they opened stores in Benton Mills, (Bagby), Mount Bullion and Mount Ophir in addition to the Bear Valley store. A fire in 1869 destroyed the first store and they relocated to this site. After the death of Louis in 1883, Elena continued to run this store. This building was reconstructed after a devastating 1897 fire. The Mrs. E. Trabucco store continued operation until 1912. Louis and Elena Trabucco are buried in the nearby Bear Valley Catholic Cemetery. Currently this is the home of their great-grandson David Trabucco.
