Rosaly is of Latin origin, derived from the word 'rosarium', meaning 'rose garden'. It is a unique and elegant feminine given name that has gained popularity over time. In the Middle Ages, it was often used as a shortening of longer names like Rosamund or Roswitha. The name Rosaly is composed of two elements: 'rosa', which means 'rose' in Latin, and '-ly', a suffix denoting association or possession. Therefore, the name could be interpreted to mean 'like a rose'. Rosaly has also been associated with roses due to its phonetic similarity with the flower's name. The name is often spelled Rosalie, Rosalía, Rosalia, or Rosalind, but Rosaly is a less common and more distinctive version. It gained some prominence in the late 19th century when it was used by several notable figures, including American novelist Rosalie de Charmoy and French poet René-François-Armand (Rosalie) de Gourmont. However, despite its historical usage, Rosaly remains relatively uncommon today, making it a unique choice for a baby girl's name. In terms of numerology, the name Rosaly is associated with the number 6, which signifies love, balance, and harmony. In some cultures, the name may also have symbolic meanings related to beauty, grace, or nature.
The name Rosaly experienced a significant increase in popularity from the late 20th century onwards, with a notable spike starting around the year 2000. The highest number of births recorded in any single year was 25, which occurred in 2019. However, it's worth noting that the overall trend shows fluctuations over time, with some years having fewer than 10 births and others having more than 20.
