I thought I would post this link to a document from the Notary P. Padthuysen collection (from 1698). It deals with Dona Manuela Miranda, widow of Don Manuel Hierro Lopes de Castro, as well as Dona Leonor Hierro Lopes de Castro, Don Sebastian Cortisos, Don Joseph Manuel Cortisos (Marquis de Villa Flor), Sebastian Hierro Lopes de Castro (lord of Castleforte, and others). According this book, The New Christians of Spanish Naples 1528-1671: A Fragile Elite, they were powerful conversos. https://books.google.com/books?id=1HPB1AmlwdYC&pg=PT119&lpg=PT119&dq=manuel+lopes+hierro+de+castro&source=bl&ots=WOXV-C_QAT&sig=ACfU3U1vNArDeg214SMbo7Ik9h0pJLgXTw&hl=en&sa=X&ved=2ahUKEwim8tSju6viAhUq01kKHbAOBTc4ChDoATAEegQICRAB#v=onepage&q=manuel%20lopes%20hierro%20de%20castro&f=falsehttps://archief.amsterdam/inventarissen/inventaris/5075.nl.html#NOTC01373000314
