Here is an idea for you, Momma.
If you look for them on
The Web's Largest People Search by Background Check, Public Records Search, E-Mail Address - Find People and Search Business at PeopleFinders.com and they are married, or sharing things financially in some way, it should show up. I have used the free part of that site many times to locate people. On the free part you can often find the married and maiden names of people, who their relatives are, how old they are (I have found that this is usually off by a year), where they have lived and presently do live and sometimes the names of businesses that they presently have or have had in the past. It's pretty cool and free!
After that, if you do know for sure as to where they live, or have lived, you could see if any court records are available in those counties. More and more, court records are available online. I do know that when they are, and some kind of legal action has taken place through a court, and if the records are available online, that you can often find records where spouses will be listed, if that spouse is one of the persons involved in the case. I know that in Iowa, divorces are listed in the online court records. There are many other things that can be listed in online court records that could be listed here. It does depend upon the particular site. Sometimes you have to pay to use the online services for court records. Oftentimes, you do not.
Just to get you started after, if you choose to use
The Web's Largest People Search by Background Check, Public Records Search, E-Mail Address - Find People and Search Business at PeopleFinders.com here are a couple other searches that you might like to click on in order to see if any court records are available online in the state of Louisiana.
Louisiana Court Records - Google Search and
Louisiana County Court Records - Google Search
Just to note: I have looked for court records in Louisiana, but haven't been able to find any online yet. That doesn't meant that they aren't out there somewhere, though. The information that you might find on PeopleFinders.com might tell you what you want to know.
Are there perhaps some other relatives that you might be able to ask concerning this?
Just some thoughts for you...
