I found that same death record on the FamilySearch site [Mormon site] and his initials were picked up as "J.J.". His parents were listed as A.D. Lee and Virginia Verrit [Verret]. I tried finding this couple in 1920, but did not find them. I also did not find death records which I find strange. The LA death records begin in 1911 and they would have died after 1916. That is assuming the children were really orphans.
I'll keep looking.
Hope this helps.
