I hope this doesn't post twice. I'm researching Duplessis families from New Orleans and Plaquemines Parish. I'm having a hard time locating Silico Duplessis born around 1840's-1850's. He only shows up on the census one time on the 1920 census. He shows up living next door to his son Robert, daughter Linda and other son Louis. I haven't been able to locate him anywhere else. It's like he just show's up age 65 in 1920. Also searching for information on Orelia Rochon & Phoebe Carnin (this were also daughters of Silico or Selicour.
