Hi,
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.
Cheryl
