Born Adélaïde-Marie-Emilie Filleul in Paris, Souza-Botelho married the comte de Flahaut de La Billarderie and became a noted late eighteenth-century Parisian salonnière. In 1792, events of the revolution forced her to emigrate, first to England, then other locations in continental Europe, before returning to Paris in 1798. She met and married the Portuguese nobleman Dom José Maria de Souza Botelho in 1802. She authored several novels, including Adéle de Senange, ou lettres de Lord Sydenham (1794); Charles et Marie (1802); and Eugène de Rothelin (1808), among others.
