Filbert, derived from the Latin 'Filicarius', meaning 'pertaining to hazelnuts', is a distinctive and uncommon given name of Germanic origin. It was popular among medieval clergy, notably Saint Filbert, the seventh-century Bishop of Meaux in France. The name Filbert fell out of favor during the modern era but has seen some recent resurgence as parents seek unique names for their children.
"The name Filbert experienced varying popularity throughout the years, with the highest number of births recorded being 13 in 1956 and again in 1938. The most consistent period for this name was during the 1910s to the early 1930s, where it maintained an average of around 8 births per year."
