Ada LaBostrie was the wife of traiteur Gene LaBostrie and was also a close friend to Alec and Abigail Holland. She lived near the town of Dogpatch, outside Houma in Terrebonne Parish, Louisiana. Ada assisted Abby Holland when she was enduring her difficult pregnancy.
Ada nearly became a victim of serial killer/faith healer Father Tocsin. After attending one of Tocsin's tent revivals, Ada was poisoned with strychnine. She found enough strength to crawl back to Gene and the Swamp Thing who then used his powers to purge the poison from Ada's body. For revenge on the attack on his wife, Gene manipulated Father Tocsin into killing himself. 
- Like her husband Gene, Ada was of Cajun descent.
