Unknown 1st wife of Dr. Formy-Duval "AKA The Princess"

From https://jefpublications.wordpress.com/carolina-chronicles-stories-f.... By Jack E. Fryar, Jr.

The Formy-Duvals had made it safely to their new home. Once ashore the doctor and his wife set out for St. Domingue, where King Louis had granted him lands in the 1780’s. Some say he owned a sugar or coffee plantation there, though little is known about the time the Formy-Duvals spent in Haiti. The couple settled into a life as country planters, and not long afterwards the family grew with the birth of John Gerome Prospier Formy-Duval around 1789, and again around 1790 when Henrietta Formy-Duval was born. Alexander, the last of the children born to Dr. Formy-Duval and The Princess, was born in 1792.
