Etymology of Mulder

What does the name Mulder mean?

The origins of the Welsh name Mulder go back to the ancient Celtic culture that existed in the hills and Moors of Wales. The forbears that initially held the name Mulder once lived in or near the settlement of Mogridge in the southwestern English county of Devon. The surname Mulder belongs to the category of habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads.

Early Origins of the Mulder family

The surname Mulder was first found in Breconshire (Welsh: Sir Frycheiniog), a traditional county in southern Wales, which takes its name from the Welsh kingdom of Brycheiniog (5th-10th centuries), where they held a family seat from very ancient times, some say well before the Norman Conquest and the arrival of Duke William at Hastings in 1066 A.D.

Mulder Spelling Variations

There are relatively few surnames native to Wales, but they have an inordinately large number of spelling variations. Early variations of Welsh surnames can be explained by the fact that very few people in the early Middle Ages were literate. Priests and the few other literate people were responsible for recording names in official documents. And because most people could not specific how to properly record their names it was up to the individual recorder of that time to determine how a spoken name should be recorded. Variations due to the imprecise or improper recording of a name continued later in history when names originally composed in the Brythonic Celtic, language of Wales, known by natives as Cymraeg, were transliterated into English. Welsh names that were documented in English often changed dramatically since the native language of Wales, which was highly inflected, did not copy well. Occasionally, however, spelling variations were carried out according to an individual's specific design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations could be indicated by minor variations. The spelling variations of the name Mulder have included Muggeridge, Mugeridge, Mugridge, Moderidge, Modridge and many more.

The Mulder 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: Dat deus incrementum
Motto Translation: God gives increase.
