JOHN
As described in historical dictionaries
Patronymica Britannica (1860)
JOHN. This baptismal name, -which is of Norman introduction, has rarely passed into a surname. The Lond. Direct, for 1852 affords but one instance. It has been, however, the source, in various modified forms, of a cousideralle number of names, some of which are amongst the most common in the whole circle of our nomenclature. Its immediate derivative, Johnson, and its Welsh genitive form, Jones, substantiate this assertion ; but we have besides Johns, Johues, Joanes, Jobncock, Janson, Jannings, Jennings, Jenks, Jeukyn, Jenkins, and Jinkius, Jenkinson, and perhaps Janes and Jenson. The Flemish nickname Hans from Johannes, seems to be the root of Hanson, Hancock, &c. Jack and Jackson might seem to claim the same parentage, but I think there is more reason for affiliating them upon James (See Jack).
