Mariana Pingron Bonifay wrote her will on 16 September 1825. In her will she was good enough, or astute enough, to leave us with some biographical details, some of them sketchy, but useful. She gives the names of her parents and where she was born; where she married and whom, but not when; and the names of her children, both with her husband Joseph and with her business partner, Carlos Lavalle.
Two paragraphs from the first page of her will are shown above giving this information about her life.
Mariana died on Saturday, 12 September 1829, in Pensacola, and was probably buried in St. Michael's Cemetery.
