Utilizing the book Historic Louisiana Nails: Aids to the Dating of Old Building by Jay D. Edwards and Tom Wells.
If the Manor House had at least three different periods of construction then the nail study should help to clarify this.
A total of 35 nails were removed from the Manor House and studied.

Because both nails found in privy/washroom correspond to the nails in Period Three it must have been added at the same time.
Quantity 0. All nails associated with the Portico including the ones for the two exterior doors were modern round heads, beginning heavy use 1879.
Conclusion:
If the premise that the heavy use of nail type to be the construction date, then the nail study of the Buttercup plantation Manor house suggests that Period One and Two were built after ca. 1815 (Terminus ante quem: The "time before which" a building cannot have existed, because it's original nails were not yet manufactured) but before Period Three (ca. 1834). Because Period One has all the same characteristics and Period Two has majority of its nails with differing characteristics than Period One, they were probably built at different times within the dates of 1815 to 1836.
Period Three was built after ca. 1834 (Terminus ante quem).
They were still using hand forged rose-headed nails for clinching in batten doors in ca.1834 because they were found in the batten door of the privy/washroom.
The Portico and the two exterior doors upstairs going to it were added after ca. 1879.
The nail study is one of the factors that help to validate the three periods of construction within the Manor House of the Buttercup Plantation.
