When Livermore died in 1858 , he left behind Josefa and eight children . He was buried at Mission San José , but his grave was " lost " for over 100 years . The 1868 Hayward earthquake destroyed the church and it was replaced by a wooden structure . When that was torn down in 1981 , workers discovered his original grave marker
