Primitive Folk Art Lady with Feather and Leaf

This is a primitive folk art oil on canvas of lady with a feather in her hair and holding some sort of plant leaf.

The canvas is 30 x 24. I am asking for opinions as to age, subject matter, and origin, etc.

I've had her for a few years and never sought information before, but find her to be an interesting person.

She was purchased from an estate in Connecticut.

Experts on line found the original of my painting.  She is part of the Rockefeller Collection of  Folk Art at Colonial Williamsburg.  Apparently she is an early copy of her or is based on her.
