"Gerry is a name of Irish origin and means 'spear ruler'. It's a variation of the medieval name Gerard, which was derived from the Germanic elements 'ger' meaning 'spear' and 'hard' meaning 'strong, brave, hardy'. The name Gerry was popularized in the mid-20th century, particularly in English-speaking countries. Throughout history, several notable individuals have borne this name, including American actor and director Geraldine 'Gerry' Mulligan and former Australian prime minister Gerard 'Gerry' Whitlam."
"Gerry" was a popular baby name at the turn of the century, with over 80 babies named Gerry annually between 1926 and 1933. However, its popularity sharply declined after World War II, dropping to single digits by the late 1960s. The last reported birth with the name Gerry was in 1995."
