I have record of Truzilla Settoon (what a name!), b: 1792 in St. Helena Parish, LA; the daughter of John and Nancy (Lanier) Settoon marrying a John Cropper; but no record of an Eli Patterson.

Other records I've seen say that John's last name was "Crossen".I don't know which is correct, but I suspect it's Cropper.The source above lists "Cropper", and it's an excerpt from letters written by the family.
Let me know about this Patterson if you have anything to add.
