I cannot find genealogical information for this sitter. An Anne Carew became a Fountayne in 1541.
From artuk.org; fixed spots and linear flaws with Photoshop and filled in shadows and increased contrast.
Anne poses almost en déshabillé with a split bodice showing off her lace chemise that slos spills out of her décolletage.
