The Welsh name Dedder comes from the personal name Tudur, an ancient Celtic name of unknown meaning. It is thought that the name, especially the form Tewdwr, may have also emerged as a Welsh version of the Latin Theodorus.

Early Origins of the Dedder family

The surname Dedder was first found in Herefordshire, where Tudor Trevor was Lord of Hereford, Whittington, and both Maelors. He was founder of the Tribe of the Marches, born in Denbigh, son of Ynyr Ap Cadforch, whose descendants intermarried with the distinguished families of North Wales.

Theodore (602?-690), was Archbishop of Canterbury, a native of Tarsus in Cilicia. "He studied at Athens, had a scholarly knowledge of Greek and Latin, and was well versed in sacred and profane literature and in philosophy, which caused him to receive the surname 'Philosopher.' At the time of Theodore's arrival the English church lacked order, administrative organisation, discipline, and culture. " 1

Dedder Spelling Variations

The Welsh have an extremely large amount of spelling variations of their native surnames to their credit. It was up to the priest or the scribe taking the official records to determine how the spoken name was to be made literal. As time progressed, the old Brythonic names of Wales were recorded in English, which was especially problematic since the English language had extreme difficulty recording the highly inflected sounds of Cymraeg. Spelling variations were, however, also carried out according to an individual's design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations could be indicated by spelling variations of one's name. The spelling variations of the name Dedder have included Tudor, Tudyr Tuder, Tudar and others.

Migration of the Dedder family

North America in the 1800s and 1900s saw the arrival of many Welsh people hoping to share in the wealth of land, work, and freedom that they felt North America held. Those who made the journey often attained those expectations, but only through an enormous amount of hard work, perseverance, and often a bout of good luck. These immigrants helped contribute to the growth of industry, commerce, and culture of both Canada and the United States. Discovered in the immigration and passenger lists were a number of people bearing the name Dedder: Richard Tudor and his wife Mary, two children and servants, settled in Barbados in 1678; Lewis Tudor settled in New England in 1654; Robert Tuder settled in Virginia in 1773..
