That has me even more confused. According to her death index, she died in Los Angeles County. The funeral home that handled her remains was in Hawthorne, which is in southwestern Los Angeles county. (A part of the greater LA area now, but probably a separate community back then.)
Inglewood Cemetery is 3 miles from Hawthorne (according to Mapquest). So, are you saying her remains were removed from Hawthorne and buried at Inglewood? If that's true, why wouldn't the cert simply says burial at Inglewood?
