Baby girl's name Claudia. English: "KLAW-dee-uh"; German: "KLOW-dee-uh"; Spanish: "KLOW-dya." This is a Roman name that is mentioned in the New Testament of the Bible. It is currently very popular in Spanish-speaking countries. Believe it or not, this would be a great tribute to a grandma Gladys: Gladys is considered the Welsh version of Claudia.
