I don't doubt her age....and I did stop a video to see a frame in the book with a lot of writings...They all said..."Beverly..Blah, blah, blah..".
Now go to Moore's page....it doesn't say Beverly and the statement is almost incomprehensible....and I'd guess it was written by a very old person....an aunt, uncle, family friend....someone who knew her from when she was a little girl. Maybe someone they knew in California who came in for Christmas.
As far as being not one seeking attention??? "I was accustomed to men flirting with me because I was well developed and I competed in Beauty Pageants". Beverly was obviously not exactly the shy type....
Bet you got hit on by older men all the time.
