I tried to send you an e-mail. I am interested in the "other" Houmas plantations that you mentioned and the information you might have. Likewise, I have information to share. I plan to be working around that area, southeast of Houmas, on a plantation that also shared the “Houmas” name.
To date, in addition to the Houmas House, the "Houmas" plantations included: Monroe, Orange Grove, Clark, Conway, Riverton, and Donaldson. Sometimes Donaldson was interchanged with Burnside/Houmas.
Please contact me directly.
