Have you done a search for unclaimed property? The California State Controller's office maintains a website to do searches: http://scoweb.sco.ca.gov/UCP/Default.aspx. If you've done a Google search you may have come upon this page: http://en.wikipedia.org/wiki/Washington_Mutual, which gives a good summary of what happened to Washington Mutual. The old Washington Mutual branch where your grandfather banked, is that now a Chase Bank? Did you try asking there?
