Don, it looks as though Ethel Lavina Spence Burton's husband's name was "Robert V. Burton". I found him & Ethel listed in the 1920 census of Oakland, Brooklyn Twp., Alameda Co., CA on page 220B with their two sons: "Dixon" Burton, aged 11 and "Jackson" Burton, aged 7, both born in CA. Dick Burton was born 6 Nov 1908 in CA and died 22 Oct 1981 in Humboldt Co., CA. I haven't found anymore data on Jack "Jackson" Burton; at least not after the 1930 census was taken. Widowed Ethel L. Burton is living in Eureka, CA with her two sons: Dick & Jack F. Burton along with Irvin E. & Floyd L. Spence (lodgers). So it looks as though Ethel L. Spence Burton's husband Robert V. Burton died between 1920 & 1930. He might have been called "Bob" since you mentioned "B. B." Burton! Please let me know if you know more about this family. Thanks.
