I have an Esnack(Eznack) in my family that was from Natchitoches, La and then later Gorum, La. Her name was Louelle, she married Johnny Setliff. They had 9 kids. I am not sure that they connect because of the spelling but there is always a chance. I do not have any more info. I have just started on this family. I know this might not help any but check for different spellings.
