Sources of given names
- Germanic names: this source is to be expected in English, which is a Germanic language, such as Alfred (cf. Sp. Alfredo), but we find many Germanic names in Spanish as well, in part because of its Visigothic past (200 years of ruling the peninsula between the 6th and 8th centuries), such as Álvaro or Rodrigo; actually, many of the Germanic names in Spanish and English are borrowed from Frankish, another Germanic language, such as Eng. Robert ~ Sp. Roberto.
- Hebrew names: these come from Biblical names and thus there are many cognates here too, e.g. Eng. & Sp. Daniel, Eng. John ~ Sp. Juan, Eng. Mary & Sp. María, or Eng. Esther ~ Sp. Ester. Names taken from the Bible have been extremely common in Christian Europe since Christianity began to spread there close to 2,000 years ago.[i]
- Roman (Latin) names: such as Sp. Julio ~ Eng. Jules or their feminine versions Sp. Julia ~ Eng. Julia; these names came to be used initially because they were names of early saints and martyrs of the Christian Church, which was, of course, the Church based in Rome (Christianity arose in the Roman Empire and from the beginning, Latin was the language of Western Christianity, which was based in Rome)
- Greek names: such as Sp. Jorge ~ Eng. George, also typically from the names of early martyrs and saints from the eastern part of the Roman Empire
