Frank 'Francois' and his wife Marie Guillemin came to San Luis Obispo County from France in 1870. Frank and Marie settled in Santa Margarita and raised their family. One son, John Babtiste and his wife Louise eventually made the Madera area their home. John was a miner, who was said to be the first person to find a thumb sized nugget in the area that led to the development of the Gambetta Mine. At any rate, I have found most of this families information. My question is this; how do I research them in France? Are there sites in English that would help me to research their family? I know that they are connected to the Chevaliers. Can anyone point me in the right direction?
