Two Jewish wills, fifteen years apart, in Puigcerdá in the early fourteenth century, enable us to reconstruct families. The reconstructions are so similar that they seem to be of a single family; but there are difficulties which make the identity less than perfect. Here, I attempt to reconcile the difficulties. The existence of only one family seems required by the overall statistics: Puigcerdá at this time had only a few hundred families altogether, and only ca. 50 Jewish families.
