Thank you for the information. I appreciate it.
I have used familysearch but am just now learning to access all of the records. There is a record on familysearch under "Mme Felin Uicknsir" that shows the parents of Antoinette Picou (1836) as Ovide "Picon" and Octavie Ferrand.
About the Deslonde question, I have a court document relating to the marriage of Armand Deslondes (son of George Deslondes and Felicite Brusle) and Odile Ferrand (daughter of Celestin Ferrand and Rosalie Rillieux) that shows Fergus Dusuau signing as security for Armand. The top of the record says Jean Baptiste Fergus Dusuau but the signature appears to be Barthelemy Fergus Dusuau.
I realize Rosalie's mother was a Dusuau but wondered if there was a connection on the Deslondes side as Barthelemy is Victorie's grandson. I attached the record. If there is a connection, maybe, at some point, it will help.
