I am searching for William H. Warren son-in-law of Alanson C. and Martha Thompson Richardson.Alanson Richardson owned land in Honcut, Yuba county and is buried in Peoria Cemetery, Brown's Valley with Nye. His daughter Elizebeth married William Warren, I can find William's and Elizebeth Richardson's marriage record but he disappears between 1869 and 1870. Did William die or divorce? Does Yuba have a Great Register that early and where is it? Does anyone know why Richardson is buried with George Nye? could Elizebeth have remarried and married Nye? I can not find any information of William Warren except born Vermont. And of course, my grandfather Alanson Coates Warren.
