The name Maria di Perna as mother on the birth record of Filomena Costan tino is presumed to be a mistake, since the birth happened at Via Costa ntinopoli 17 and the father is Giovanni Costantino; and the couple name d Rosaria di Perna and Giovanni (or Giovambattista) Costantino living at V ia Costantinopoli 17 are documented with many records. The birth record o f Filomena Costantino says her mother is Maria di Perna, but the death r ecord of the same Filomena Costantino says her mother is Rosaria DiPern a, and both records give the address Via Costantinopoli 17.
