The name Larnce, pronounced lar-ance, is of Latin origin and means 'from Laurentum'. It is believed to be derived from the ancient Roman city of Laurentum, which was located near the modern-day town of Lavernarium in Italy. The name gained popularity during the Middle Ages as a given name and has since been used throughout Europe. In some cases, it may also be considered a variant spelling of the more common name Lance.
"The name Larnce had its peak popularity between 1916 and 1923 with over 10 births each year. However, it gradually declined afterwards, with fewer than 10 births per year from 1924 onwards."
