Roy Precious - Antiques & Fine Art has dated this piece to the 1700s.

An elegant and fashionable silk shoe peeps out from under her skirt; the way the flowing robes are shown suggests a feeling of movement as if the sitter has just walked in and paused for a moment.
The sitter's identity is not known, but, tantalisingly, on the frame a fragment of handwritten label survives

"....ell of Lanherne.....ed......7th Baron".
The most notable family in Lanherne, Cornwall were the Arundells, an ancient and noble family. Might this label have once read ".......Arundell of Lanherne married ......7th Baron"?

D'Agar's manner is directly comparable in style to Michael Dahl, whose treatment of portraits of children in particular is similar. The size, c. 60 x 40 inches would seem to have been a standard dimension for Dagar's child full-lengths - and they often employ the same staging device, whereby the sitter is placed on a terrace, a landscape beyond. This portrait also employs D'Agar's trick of trailing drapery just cropped by the edge of the canvas.

CHARLES D'AGAR (1669 - 1723) came to England with his Huguenot father Jacques in 1681, settling here permanently after a stay in Copenhagen by 1691. He had a good practice, numbering such people as the Duke of Buccleuch and Lord Bolingbroke among his patrons.
