I am looking for information on my husband's great great grandparents. Giuseppe "Joseph" Solari and his wife, Anne Sturla Solari immigrated with their family from Italy to Sonoma Co in 1870. Anne is widowed and living with a son, David, son John, and a son's widow Rosetta Solari in Vallejo in the 1910 census. I have been unable to find her in the 1920 census. I believe that she died between 1910 and 1920. It is possible that she is buried in Marin Co. since the Solari family lived very close to the county line. Can anyone help with further information?
