Sigfredo is a distinctive and unique given name of Latin origin, derived from 'Sige-fre' which means 'victory peace'. It was quite popular during the Middle Ages but has since become less common. In Spanish-speaking countries, Sigfredo may be used as an alternative to Sigmund or Siegfried. The name has not traditionally been associated with any specific saint or religious figure.
"Sigfredo saw its peak popularity in the late 1950s and early 1970s, with over 14 births each year from 1958 to 1972. After a steady decline, it remained consistent around 6-7 births per year from 1980 to 2000."
