Francisco Jr., a variant of the Spanish name Francisco, is of Latin origin and means 'free born'. It is derived from the German name Franz, which itself originates from the Frankish name Franco, composed of the elements 'francus' meaning 'French' and 'cisk' meaning 'kiss'. The name gained popularity due to St. Francis of Assisi, an Italian monk who was revered for his generosity and kindness. 'Junior', or Jr., is added when a person has the same name as their father.
"Its popularity peaked in 2003 with five births that year, but overall it remains quite rare."
