The other day, I found a blog run by the current owner of Layton castle, which only has a couple of posts. They are very interesting though! The first post is about a former enslaved resident of the castle named Annette. The second post is about a little girl ghost who haunts the castle. You can read them here: https://www.laytoncastle.com/blog .
Update 8-15-2022: Coincidentally, I found the little girl ghost’s obituary in the New Orleans Times-Picayune, July 14, 1901. She was about ten or eleven when she died:
The community is saddened by the death of little Georgette Layton, which occurred on Wednesday last, after a lingering illness.
