Irby is a unique and distinctive given name, derived from the Old Norse personal name Yrbi, which means "famous spear". This name has been predominantly used as a surname in English-speaking countries but is now also appearing as a given name, adding a touch of rarity and individuality to those who bear it. Irby was once associated with the small village of Irby in Cheshire, England, which may have contributed to its popularity as a surname. Today, Irby remains an uncommon yet appealing choice for parents seeking an unusual yet meaningful name for their child.
"Annually, between 1898 and 1943, the name Irby was given to five newborns each year except for a peak of six in 1916, resulting in a total of twenty-six babies named Irby during this period."
