Pair of portraits from the early 18th century

Pair of portraits, a woman and a man painted in a medallion style, the woman is richly dressed in an evening gown with lace, embroidery, and jewellery, styled in the Fontange fashion, while the man is wearing a simple velvet dressing gown but is still wigged. On the reverse, one can see the surnames of the depicted characters as well as the date 1715. It seems that the role of the male character might be "Protestant pastor" as indicated on the back of the canvas. Paintings on their original canvases on which old restorations have been carried out. Frame from a later period, probably from the Louis XVI era.
