Check the info I sent you. The name is Jean Rebecca BLACK [may be Mrs]; b Washington 1897/98 I doubt she is the same person who d 1980 San Diego. Have you checked with the San Joaquin Library for an obit for George?It may provide the answers you need, and save you time/effort.
We know for a fact the 1st wife was Pearl Lillian ANDERSON, not probably.Too many Pearls b 1909-11 North Dakota. Have you tried familysearch.org yet?It's a wonderful site!
