I represent Don Eugenio Antonio Sierra, a European man born in Castile, Spain. At the time of the 1820 census of Pensacola, I was 59 years old and married to Doña Francisca Dauphin Sierra. I made my living as a surgeon. Our household was large and included my six children; my widowed elderly father-in-law, Don Francisco Dauphin; and my brother in law, Don Santiago Dauphin. I lived to be 99 years old and am buried in St. Michael’s cemetery.
Don Dr. Eugenio Antonio Sierra
