So who were "The Coonies"?

When the Bracken's and sheriff are looking for Desiree, they comment that "nobody knows where they are but The Coonies" and they show them going to some shack on the river, but we never see the interaction. I think there was an earlier comment at the beginning from Ben to Deputy Bily Boy about how "Coonie tail is much easier to get than that Thibodeau girl" or something like that.

So where "The Coonies" just another Cajun family? Was it a brothel?
