Jordan m. Hebrew הַיַּרְדֵּ֔ן, the name of the river in Palestine in which Jesus was baptised by John the Baptist. The origin of the name is uncertain, but is possibly derives from a root meaning 'to descend, flow down'. Withycombe s.n. Jordan hypothesizes an Old German Jordanes of independent origin (deriving from Old Norse jǫrð 'land, earth'), but Morlet II:66b notes that the name was adopted as a Roman cognomen and then adopted by Christians. The name's popularity dates from the Crusader era, though it is found in France from the 9th C onwards.

The name of a 10th C bishop of Poland. Wycliffite Bible (1395): Jordan.

The English diminutives Jud and Jude are witnessed in 1379 in the relational bynames Judsoñ (WRYPT1 p. 162) and Jude Doghter (WRYPT1 p. 163).
