Our information on the Tunis Baruch Lousadas can be sourced in refs 171, 185 and 186. Perhaps Elias and Benjamin descended from an earlier generation with Jacob Baruch Lousada together with Isaac Baruch Lousada appearing in Tunis in 1686 (from ref 185 p469). They were probably related to the Livorno Levi Lousadas some of whom also moved to Tunis.
