Pierre Louis de Saffon (1724, France â August 1784, Demerara) was a French duellist who settled in Demerara after killing his brother in a duel. After moving to South America, he became a rich planter and owner of multiple estates; he named two of these Le Repentir â the repenting, and La Penitence â the penitence, as a memorial to his brother's death. He died in 1784; he left the revenue from his estates to provide for 10 orphans until they turned 16.
