Petrina, of Latin origin, is a feminine given name derived from the Roman family name Petraius, which was in turn derived from the Latin word 'petra', meaning 'rock' or 'stone'. This name has been historically used to denote strength and steadfastness, characteristics associated with rocks and stones. The name Petrina gained popularity in the Middle Ages due to its association with Saint Petronilla, who was believed to be the daughter of Saint Peter, one of Jesus Christ's apostles. However, it remains relatively uncommon today, offering a unique and elegant choice for parents seeking an unusual yet meaningful name for their child.
Over the course of these years (1900-2011), there's a notable trend: Petrina was quite popular from around 1949 to the late 1970s, with a peak in 1969 (62 births) and consistent high numbers until 1973. However, it seems its popularity began to decline sharply thereafter, reaching as low as 6 births per year between 2000 and 2005, before slightly increasing again from 2006 onwards. Overall, Petrina had a total of 2107 births over these 112 years.
