The 1860 census shows all the members of this family born in France except the youngest daughter Leonet b 1852 in Arkansas. This doesn't agree with some others' history, but that's all I have to go on. I have not found them in 1850. I did find some of the other families (Pevetos, Fogles and Laboeufs on earlier censuses. If the 1860 census is accurate they arrived in Arkansas between the birth of Theodore (c1845) and Leonet (c1852. The Ouachita County website has an article on Frenchport that includes some info on these families. The story of their arrival may fit the Pedrons. It does not fit the other families who were in Louisiana as early as 1805 and show up in Arkansas about 1836.
