What is "araujo"

Araújo or Araujo or Arauxo is a Galician and Portuguese surname. The surname Araújo is of toponymic origin derived from a place in the vicinity of the Miño River where a Crusader Knight of French Noble descent, Don Rodrigo Anes, was rewarded with reconquered Iberian lands during the Reconquista. The poisonous plant with white fragrant flowers known in Latin as Araujia sericifera was named after the botanist António de Araújo e Azevedo, 1st Count of Barca (1754–1817). The surname Araújo seems to be a habitational name in Portugal and can be found in and around Portuguese cities such as Coimbra, Elvas, Estremoz, Lisbon, Torre de Moncorvo, Monção, Serpa, Setúbal, and Vila Verde.
