‘fl.’ = the span of dated catalog records matching the name forms as author/recipient. Outlier years usually mean a retrospective mention, a later copy, a homonym, or a record whose own date carries a low confidence flag — check the records, not this line. Counts are of DISTINCTIVE name forms; bare family surnames (Argüello, Carrillo, Castro, Estrada…) are deliberately left unattributed rather than guessed.
