Putting in WOOD for MMN and BELO for Father's surname in the same database gets us LINEBARGER, LELA PEARL, b.01/25/1894, also from Missouri, so she looks a lot like a sister. She died in Tulare County.
Finally, I used a web-based phone book http://wp.superpages.com/people.phtml?SRC=http://wp.superpages.com/people.phtml?SRC= with surname BELO, town MODESTO, and "Include Nearby areas" checked. I got two hits. Using MERCED as a town, and again leaving "nearby" checked got me another.
