I've been able to find these families and they are all well documented on Ancestry.com. Many people don't like Ancestry and say it's full of false and misleading information. I'm not one of those people. The problems come when people just "click" and add people from other people's public member trees without doing any research to see if documentation exists to prove those family relationships.
While I haven't been able to find a marriage record for Evelyn and Aubrey Arnold, someone has a copy of their marriage license in their private tree. I didn't use this information to find Evelyn's maiden name, I found that on Family Search, located on the death record for Evelyn and Aubrey's son, Aubrey Howard Arnold.
If you can afford one, a subscription to Ancestry.com is invaluable. If you can't afford a yearly subscription, they allow you to purchase monthly access, which gives full access and is renewable monthly. I used this for many years until I finally was gifted with a world yearly subscription by my husband. :)
I've been able to find the parents of Evelyn, and possibly even her grandparents on her maternal side; the parents and grandparents of Aubrey, the graves of almost all of these people, and many of their descendants, all using Ancestry.com's images of documents and links to other sites. If you haven't discovered it yet, Louisiana allows one to look up death records on the Secretary of State's website: www.sos.la.gov. Once there go to:
Home > Historical Resources > Research Historical Records > Locate Historical Records > Louisiana Death Records. You can search by name, by year, by Parrish, or any combination of those things. I was able to find the death date for Mollie Dell Markham Allison in this way.
I wish you success in your ancestor-hunting. It's very addictive. :)
