Lots of unanswered questions here.

Here is some info on the cemetery where she was purportedly buried.

Union Cemetery - Brentwood, CA

Why would she be interred here? Why not in the Los Angeles or San Diego area where most of her life was spent? Brentwood (NOT 90049, the affluent section of Los Angeles) where this cemetery is located is in the East Bay area of Contra Costa County. Is that perhaps the home of her alleged father? I have seen nothing to indicate that she had friends, family or other connections there.

Search results on findagrave.com list 1224 individuals buried at Union Cemetery but none with a last name of Haley. So that just leads to additional questions.
