My information has Marie Ociana (Oceana) MATHERNE, b. 20 Jan 1896 in Montegut, Terrebonne, LA. She was the daughter of Joseph Anatole MATHERNE and his second wife Augustine Clelie PONTIFF. She married William DUFRENE. There were many marriages between MATHERNES and DUFRENE/DUFRESNES in this area.
I have Emily FRICKEY to be the wife of Francois "Frank" DUFRENE. She died 31 Aug 1944 according to my notes. She was the mother of Frazie Marie DUFRENE who married Cyril Oliver MATHERNE. Perhaps this is a different Emily FRICKEY.
Oceana's sister Clementine married Mahoney DUFRENE; her brother Hildes married Louvinia DUFRENE.
