Izannah's Molds?

Recently I was reading German Papier Mache Dolls 1760-1860. In it they show some pictures of wax models used to make Voit molds. The wax models are so beautiful! And it's amazing that they've survived so long. This got me to wondering:

"What happened to
Izannah Walker's doll molds?"

Did they get left to a family member? A friend? Did they get broken upon her death? Are they moldering at some roadside antique shop somewhere in America? And would anyone know what they are if they saw them there?

There are a few dollmakers that I respect who have made a doll in the way that Izannah originally did - with a hard core, covered with layers of fabric that had been impregnated with something that stiffened the fabric and set in a mold. This was then covered with batting, which was covered with stockinette which was covered with paste which was painted. Phew! A lot of steps. And yet we see the longevity that the process gave her works.

Inquiring minds want to know a lot about Izannah.
