WHAT WE KNOW:
 The frame (4 1/8" x 5 1/8"), top paper with decoration, glass, underneath black paper, and underneath black fabric are all original.  The back paper (with numbers on it) appears to be original.  Obviously, the straight pins holding all together, are not original.  The curly front part of her hair and her collar are pen & ink decoration.  Behind the face is black paper and behind the dress is black cloth.  There is an obvious shadow on the black cloth in the shape of the dress (pictured, but shadow is not as obvious in pic as in real life).  The brown paper is fragile, but is complete.  The frame is pine with gold paint.  Some whitish gesso shows.  The frame is nailed at corners with square headed brads.  The glass is bubbly & wavy.  The little metal ring on top (for hanging) is tied to the frame with tiny wire which pierces the wood and opens like a cotter pin on other side.

 Quite visible on top of the frame, in pencil and in script, is "Diantha Mascraft" and the number "6" to the lower right.  Please look at the name in the picture below: the first letter of the last name is an "M" and not "At" (what looks like a cross on a "t" is grain in the wood.  The word is quite clearly "Mascraft".  The young lady looks older than six years, but who knows.

INFORMED SPECULATION:
We've done a bit of research on the name Diantha Mascraft and find only one person with this name in ancestory.com.  Diantha was born April 22, 1812 in Woodstock, Windham County, Connecticut.  She was the daughter of Jacob (born 1781 in Woodstock) and Asentha Wakefield (born is Killingly, Connecticut).  Both of these families trace to 17th Century Connecticut, Maine and Mass.  Diantha is noted on p. 280 & p. 443 in the Barbour Collection of Connecticut Vital Records, Windham County, Connecticut. Pt. 1. There is also note of Diantha in "History of Woodstock, Connecticut, Gen. of Woodstock fams.", by Clarence Winthrop Bowen, vol. 111, p. 285 and Diantha (Mascraft) Copeland in Vol. 34, p. 230.
Was unable to access these records, but can document the references.

 Can't imagine this silhouette is none other than Diantha Mascraft,
about age 16 accomplished in 1828, in Woodstock, Connecticut
(if she were 6 yrs. silhouette was made in 1818).
