Hi Paul, I did look up the parties you mentioned. Did you verify the two marriages with the Monterey Recorder-County Clerk's office, www.co.monterey.ca.us/recorder/ ?
I did find the Dyers, Swopes, Dillards and Wassons Unforgotten Family Tree, trees.ancestry.com/tree/15043833/person/203613104 with the two marriages but there are no sources listed.Therefore, those "facts" need to be documented especially before you try to figure out who William Erwin Tucker was.
After you verify that she DID marry William, then I can do some research to find out more about him. Successful Searching!
