Louisa Charlotte Webb

Burr may have had two illegitimate mixed-race children with Mary Emmons, aka Eugénie Bearhani (phonetic spelling). She was a servant in the Philadelphia household. She was an East Indian from Calcutta and had been enslaved in Saint-Domingue which was brought by her master to Philadelphia, where she became free; Pennsylvania abolished slavery after the Revolutionary War. Their children were Louisa Charlotte (born 1788) and John Pierre Burr (born 1792).
