Probably Rhode Island or Connecticut, ca. 1830's. Watercolor on wove paper in a terrific figured-burl frame with corner-blocks. Characteristic Davis features include a black dress, full-face angled a bit to the right (not in profile), blue and white highlights, and mid-length. Note the tiny hands holding a book. Exceptionally puffy sleeves on the forearm fashionable in the early 1830's, with lace trim. Frame size about 7 5/8 inches x 7 1/8. Reference: See "Three New England Watercolor Painters" pp 42-55 for other portraits by Davis.
