This sitter has been traditionally identified as Sir John Rarlace but J. J. Foster (Samuel Cooper and the English Miniature Painters of the XVIIth Cenury, 2 vols., London, 1914-16) records a miniature of Sir John Barlace or Borlase painted circa 1658. No further description is given of the work although it was then owned by Lord Vernon and is referred to in notes on a painting of Sir John Borlace, 2nd. Bt. shown at the New Gallery, Van Dyck, 1886, no. 91
