While the ancestors of the bearers of Jonass came from ancient Welsh-Celtic origins, the name itself has its roots in Christianity. This surname comes from the personal name John, which is derived from the Latin Johannes, meaning "Yahweh is gracious."

This name has always been common in Britain, rivaling William in popularity by the beginning of the 14th century. The feminine form Joan, or Johanna in Latin, was also popular, and the surname Jonass may be derived from either the male or female name. "Though its origins are in England, the surname is predominately held by people of Welsh extraction due to the overwhelming use of patronymics in Wales from the 16th century and the prevalence of the name John at that time." 1 "Next to John Smith, John Jones is probably the most common combination of names in Britain." 2

Early Origins of the Jonass family

The surname Jonass was first found in Denbighshire (Welsh: Sir Ddinbych), a historic county in Northeast Wales created by the Laws in Wales Act 1536, where their ancient family seat was at Llanerchrugog.

The name Jones, currently one of the most prolific in the world, descends from three main sources: from Gwaithvoed, Lord Cardigan, Chief of one of the 15 noble tribes of North Wales in 921; from Bleddyn Ap Cynfyn, King of Powys; and from Dyffryn Clwyd, a Chieftain of Denbighland.

All three lines merged in Denbighshire about the 11th century and it is not known which of the three can be considered the main branch of the family. Later some of the family ventured into England. "[The parish of Astall in Oxfordshire] was formerly the residence of Sir Richard Jones, one of the judges of the court of common pleas in the reign of Charles I.; and there are still some remains of the ancient manor-house near the church, which are now converted into a farmhouse." 3

"Llanarth Court [in Monmouthshire], the admired seat of John Jones, Esq., is a handsome and spacious mansion, the front ornamented with an elegant portico resembling that of the temple of Pæstum." 3

Jonass Spelling Variations

Although there are not an extremely large number Welsh surnames, there are an inordinately large number of spelling variations of those surnames. This variety of spellings began almost immediately after the acceptance of surnames within Welsh society. As time progressed, these old Brythonic names were eventually were recorded in English. This process was problematic in that many of the highly inflected sounds of the native language of Wales could not be properly captured in English. Some families, however, did decide to modify their own names to indicate a branch loyalty within the family, a religious adherence, or even a patriotic affiliation. The name Jonass has seen various spelling variations: Jones, Jonas, Jone, Joness and others.

United States Jonass migration to the United States +

The Welsh migration to North America in the late 19th and early 20th centuries contributed greatly to its rapid development. These migrants were in search of land, work, and freedom. Those Welsh families that survived the long ocean journey were critical to the development of new industries and factories, and to the quick settlement of land. They also added to an ever-growing rich cultural heritage. A search of the immigration and passenger lists has shown a number of people bearing the name Jonass:

The Jonass Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Heb dduw, heb ddim
Motto Translation: Without God, without anything.
