Abstract: We prove that if and are smooth varieties and is an elliptic fibration with singular fibers curves of types I with , II, III and IV, then the relative Jacobian of , defined as the relative moduli space of semistable pure dimension one sheaves of rank 1 and degree 0 on the fibers of , is an elliptic fibration such that all its fibers are irreducible. This extends known results when fibers are integral or of type I.
