A biographical sheet on Millo Castro Zaldarriaga records the date 14 November 1964 in her life data, though its specific significance (birth, death, or commemoration) remains unclear.
On 14 November 1964, a date that appears in a Spanish‑language educational sheet on Millo Castro Zaldarriaga, her name is associated with a biographical entry highlighting her achievements as a Cuban percussionist and artist.[1] The document lists “14 de noviembre de 1964” under “Datos de vida” without specifying whether this marks a birth, death, or commemorative milestone, and it presents her simply as a notable figure in Afro‑Cuban percussion.[1]
Because other biographical references, including Wikidata and derivative summaries, give her lifespan as 1922–1995, historians and educators treat the 1964 date cautiously, regarding it as a documented but unexplained life‑related datum rather than a confirmed vital date.[4][1] Its presence nonetheless illustrates the fragmentary nature of the surviving record on Millo’s life and the challenges of reconstructing the careers of women musicians whose contributions were long marginalized.
The significance of 14 November 1964 therefore lies less in a specific event and more in what it reveals about the state of the sources: Millo’s story has been preserved piecemeal, often through later educational materials and children’s literature rather than through comprehensive contemporaneous archives. For rigorous historical work, the date is best flagged as a known but ambiguous reference point, reminding researchers to seek out additional primary documentation—such as Cuban press reports, concert programs, or civil records—to clarify her chronology and fully situate her within twentieth‑century Cuban musical history.
