This name derives from the Ancient Greek name “Eulalía (Ευλαλία)”, composed of two elements: “eû (εὖ)” (well) plus “laléō (λᾰλέω)” (talk, chat, chatter, prattle, speak, chirp). In turn the name means “to talk well”. Saint Eulalia was co-patron saint of Barcelona, was a 13-year-old Roman Christian virgin who suffered martyrdom in Barcelona during the persecution of Christians in the reign of Emperor Diocletian. There is some dispute as to whether she is the same person as Saint Eulalia of Mérida, whose story is similar. Eulalia of Mérida was a young Roman Christian martyred in Emerita, the capital of Lusitania (modern Mérida in Spain), conventionally during the persecution under Diocletian and Maximian.
