There is an Edwin Douglas born about 1886 in Missouri in Modesto on the 1930 census. He is single and his relation to H of H is "lodger".
There is a Belle Douglas on the Roots Web California Death Index. She was b. 09/21/1871 in Nevada and died in San Joaquin county, one county north of Modesto, on 07/16/1953.
Are either of those the people you seek?
Complete strangers - selfless, gracious, well-read, warm, witty and devilishly handsome, but not related - will help you, sometimes, but "living in Modesto 1932" doesn't give us much to go on. Were they brother and sister, 3 and 5 years old at the time? A married couple in their 90's?
