POTOSA
POTOSA. Potosa was believed to have been the wife of Julien DUBUQUE although his marital status is uncertain. In personal letters, Dubuque referred to a "Madam Dubuque." He is believed was referring to Potosa, the daughter of Chief PEOSTA. No mention of a wife was made during the months settling his estate has led many to consider that if a wife existed she was a Native American who returned to her tribe after his death.
She is believed to have been the mother of ROLLING CLOUD.
