Descendents of Amedee and Elizabeth HERMAD ORY

I am looking for descendents of Amedee(1883-1969) and Elizabeth(Elise, Elisa) Hemard(1890-1980) Ory from Orleans Parish, Louisiana. My research has found that they had twins in 1910 - Douglas Edward Ory and Dorothy Elizabeth Ory.Douglas died in 1984 in Houston, TX.He was married to Loretta Bernice Duignan in 1959.Dorothy died in 1993 in Gretna, LA.Dorothy married someone with the last name Schneidier and then it appears she later married someone named Gelder.I am hoping to continue forward with the descendents of Douglas and Dorothy.I would also be interested in any living family members of Elizabeth Hermad named above.Thank you for any help.
