The Evangelist who was surnamed Mark, and Joanna the wife of Herod’s steward, both had received their names independently, and thus Joannes became a most universal baptismal name, given from the first in the East and at Rome. There were many noted bishops so called in the fourth century, the earliest time when men began to be baptized in memory of departed saints, rather than by the old Roman names. The first whose name is preserved is Joannes of Egypt, one of the hermits of the Thebaïd; the next is the great deacon of Antioch, and patron of Constantinople, Joannes Chrysostomos (John of the golden mouth), whose Greek surname, given him for his eloquence, has caused him to be best known as St. Chrysostom, and has perpetuated in Italy, Grisostomo; in Spain, Crisostomo; whilst the Slavonian nations translate the name and make it Zlatoust.
At Constantinople, the patriarch[patriarch] St. Joannes the Silent, at Rome, the martyr Pope St. Johannes I., at Alexandria, the beneficent patriarch St. Joannes the Almoner, all renewed the popularity of their name. The last mentioned was originally the patron of the order of Hospitallers, though when these Franks were living at enmity to the Greek Church, they discarded him in favour of the Baptist. Each of the two Scriptural saints had two holidays,—the Baptist on the day of his nativity, and of his decollation; the Evangelist, on the 27th of December, as well as on the 6th of May, in remembrance of his confession in the cauldron of boiling oil.
Thus the festivals were so numerous that children had an extra chance of the name, which the Italians called Giovanni, or for short, Vanni; and the French, Jehan.
It was still so infrequent at the time of the Norman Conquest, that among the under-tenants in Domesday Book, to 68 Williams, 48 Roberts, and 28 Walters, there are only 10 Johns, but it was flourishing in the Eastern Church, where one of the Komneni was called, some say from his beauty, others from the reverse, Kaloioannes, or handsome John, a form which was adopted bodily by his descendants, the Komneni of Trebizond.
It had come into Ireland at first as Maol-Eoin (shaveling, or disciple of John), the Baptist sharing with St. Patrick the patronage of the island; but Shawn or Seoin soon prevailed in Ireland, as did Ian in Scotland; but not till the Crusades did French or English adopt it to any great extent, or the English begin to Anglicize it in general by contracting the word and writing it John.
The misfortunes of the English Lackland and of the French captive of Poictiers caused a superstition that theirs was an ill-omened royal name, and when John Stuart came to the Scottish throne, he termed himself Robert III., without, however, averting the doom of his still more unhappy surname. It did not fare amiss with any Castilian Juan or Portuguese Joâo; and in Bohemia a new saint arose called Johanko von Nepomuk, the Empress’s confessor, who was thrown from the bridge of Prague by the insane Emperor Wenzel for refusing to betray her secrets.
As St. Nepomucene, he had a few local namesakes, who get called Mukki or Mukkel. The original word is said to mean helpless.
Double names, perhaps, originated in the desire to indicate the individual patron, where there were many saints of similar name, and thus the votaries of the Baptist were christened Gian Battista, or Jean Baptiste, but only called by the second Greek title—most common in Italy—least so in England.

The Illyrians, using the word for christianizing instead of that for baptizing, make the namesakes of the Baptist Kerstiteli.
