Did you try contacting her grandparents in KY?
There are only 3 phone numbers with that last name in Yuma. Did you try calling them - maybe it's her parents?
As an aside, I would be totally pissed off if someone posted my full name, age, hometown and a picture (regardless if it's from 20 years ago) on a some public board. Especially someone who I've had no contact with in over 20 years. And, yes, even if it's only a seemingly innocuous quilting board.
But that's just me.
