Leander Perez- Stolen land claim in Plaquemine Parish

Leander Perez- Stolen land claim in Plaquemine Parish
I have an elderly friend that would like to know if there is any ongoing efforts to reclaim land that was claimed to be stolen from them during the reign of Leander Perez Sr. in the 1930`s. It was originally a Spanish land grant. Her grandmother was actually Leanders first cousin. The land was stolen about the time oil and gas well Companies were going to be negotiating with the landowners for royalties. Imagine that. Back in the 80`s when several lawyers were involve in the effort to reclaim the land The courthouse in Pointe a la Hache in Plaquemine Parish mysteriously burned down. Imagine that. Along with death threats. The case was finally dismissed by a judge. She said in the 80`s an estimated amount of over 60 billion dollars in royalties were taken in.
There has been some success in reclaiming land with some other groups in the past in St. Bernard and Plaquemine parish.
She had plenty of documents accumulated for the effort to reclaim the land but the documents were destroyed by Katrina.

It was called the Cheniere Ronquille tract and the original name on the land grant was Juan Ronquille

We have googled around and havn`t found much on that tract.
