Geraldin is a female given name of French origin, derived from the Germanic name Gerhard, which consists of the elements "ger" meaning "spear" and "waldi" meaning "rule". This gives Geraldin the meaning of "strong in battle". It is pronounced as /ʒəʁal.dɛ̃/. The name was popularized by French author Honoré de Balzac, who used it for a character in his novel "Père Goriot". In English-speaking countries, Geraldin may be considered somewhat unusual or old-fashioned, but it has been used sporadically over the years. It is more commonly found in French-speaking countries and regions with significant French influence.
"The name Geraldin experienced periods of popularity and decline over the years, with peaks in 1988-1989 (24 births), 2008-2009 (16 births), and 2011-2012 (24 births). Despite these highs, it has been relatively uncommon overall, with just over 120 births recorded since 1964."
