For whom was Blanche's house declared "out - of bounds"?

Blanche's place was declared out of bounds for the soldiers stationed at the srmy camp near Laurel.

And for the last year or two she has been washed up like poison. That's why she's here this summer, visiting royalty, putting on all this act--because she's practically told by the mayor to get out of town! Yes, did you know there was an army camp near Laurel and your sister's was one of the places called "Out-of-Bounds"?
