Surname or Lastname
English
English : from the female personal name Isabel(l)(a). This originated as a variant of Elizabeth, a name which owed its popularity in medieval Europe to the fact that it was borne by John the Baptist’s mother. The original form of the name was Hebrew Elisheva ‘my God (is my) oath’; it appears thus in Exodus 6:23 as the name of Aaron’s wife. By New Testament times the second element had been altered to Hebrew shabat ‘rest’, ‘Sabbath’. The form Isabella originated in Spain, the initial syllable being detached because of its resemblance to the definite article el, and the final one being assimilated to the characteristic Spanish feminine ending -ella. The name in this form was introduced to France in the 13th century, being borne by a sister of St. Louis who lived as a nun after declining marriage with the Holy Roman Emperor. Thence it was taken to England, where it achieved considerable popularity as an independent personal name alongside its doublet Elizabeth.

English and Scottish : from the Middle English personal name Ma(t)thew, vernacular form of the Greek New Testament name Matthias, Matthaios, which is ultimately from the Hebrew personal name Matityahu ‘gift of God’. This was taken into Latin as Mat(t)hias and Matthaeus respectively, the former being used for the twelfth apostle (who replaced Judas Iscariot) and the latter for the author of the first Gospel. In many European languages this distinction is reflected in different surname forms. The commonest vernacular forms of the personal name, including English Matthew, Old French Matheu, Spanish Mateo, Italian Matteo, Portuguese Mateus, Catalan and Occitan Mateu are generally derived from the form Matthaeus. The American surname Matthew has also absorbed European cognates from other languages, including Greek Mathias and Mattheos.It is found as a personal name among Christians in India, and in the U.S. is used as a family name among families from southern India.

This was borne by an archangel in the Bible (Daniel 8:16 and 9:21), who in the New Testament announced the impending birth of Jesus to the Virgin Mary (Luke 1:26–38). It has been a comparatively popular personal name in all parts of Europe, among both Christians and Jews, during the Middle Ages and since. Compare Michael and Raphael.

Surname or Lastname
English
English : from a personal name that has the same origin as Jacob. However, among English speakers, it is now felt to be a separate name in its own right. This is largely because in the Authorized Version of the Bible (1611) the form James is used in the New Testament as the name of two of Christ’s apostles (James the brother of John and James the brother of Andrew), whereas in the Old Testament the brother of Esau is called Jacob. The form James comes from Latin Jacobus via Late Latin Jac(o)mus, which also gave rise to Jaime, the regular form of the name in Spanish (as opposed to the learned Jacobo). See also Jack and Jackman. This is a common surname throughout the British Isles, particularly in South Wales.

English, German, French, and Jewish : from the personal name, Hebrew Yosef ‘may He (God) add (another son)’. In medieval Europe this name was borne frequently but not exclusively by Jews; the usual medieval English vernacular form is represented by Jessup. In the Book of Genesis, Joseph is the favorite son of Jacob, who is sold into slavery by his brothers but rises to become a leading minister in Egypt (Genesis 37–50). In the New Testament Joseph is the husband of the Virgin Mary, which accounts for the popularity of the given name among Christians.A bearer of the name Joseph with the secondary surname Langoumois (and therefore presumably from the Angoumois region of France) is documented in Quebec City in 1718.

English : from the Middle English vernacular form, Maudeleyn, of the New Testament Greek personal name Magdalēnē. This is a byname, meaning ‘woman from Magdala’ (a village on the Sea of Galilee, deriving its name from Hebrew migdal ‘tower’), denoting the woman cured of evil spirits by Jesus (Luke 8:2), who later became a faithful follower. In Christian folk belief she was generally identified with the repentant sinner who washed Christ’s feet with her tears in Luke 7; hence the name came to be used as a byname for a prostitute, also a tearful woman. The popularity of the personal name increased with the supposed discovery of her relics in the 13th century.
