1795 Lady Rancliffe nee Elizabeth Anne James, married to Thomas Boothby Parkyns, 1st Baron Rancliffe by John Hoppner (British Museum - London, UK)
I could find nothing about her and very little about her husband. The engraving was done by Charles Wilkin after a Hoppner portrait.

Lady Rancliffe wears something similar to the chemise a la reine of ten years earlier in this 1795 Hoppner portrait.
