Civil War Fort at Prairie des Femmes?

According to a local lady, the Prairie des Femmes was named for  a fort located there during the American Civil War used to house women and children away from the battles along the Bayou Bourbeux, which borders the Prairie.

"Prairie des Femmes was actually named for a fort that was built to house women and children during the civil war. Although I am uncertain of the location's actual coordinates I do know it is located North of Fuselier Rd, East of Jules Lagrange Road and South West of Pointe Claire Hwy. The area is somewhere within 3 miles as the crow flies of my family home. We have found many artifacts while excavating a parcel of land bording a patch of woods. We have found Various items like dishware, utensils, the metal component of a muzzle firearm containing the firing mechanisms and trigger, grinding stones and many native American artifacts as well." 2013 TQ

While I like the romantic idea of a fort, the name Prairie aux Femmes (!!!) can be seen on this 1806 map by B. Lafon, which predates the Civil War by more than 50 years.

The notion that the Prairie des Femmes has been a place of refuge for women and children is prevalent in all of the local lore about it, and the old-timers will site that it was where the women and children took refuge during the Civil War or other dangerous times. Was there really a central place, a fort or enclosure, possibly built by the men, where women stayed safe, or is this a misunderstanding of the meaning of place of refuge?

Here is a very approximate location of the fort at Prairie aux Femmes:
