Answer 2

The name Den or Dene first appears in England soon after the introduction of surnames. It was apparently derived from the Saxon word for valley – den or dene. After the “great vowel shift” in the language of Elizabethan England, the name was spelled Dean or Deane. This word can still be found in the names of some valleys in England.

Today this surname takes several spellings – Dean, Deane, Deans, Deen and others. There is some evidence that the German surnames Dein and Dehn were anglicized to Dean in America.

Canadian censuses of 1871, 1881 and 1901 record the national origin of each person. Persons surnamed Dean or its variations usually indicated that they were of English, Irish or Scottish national origin, although there are a few instances in which German national origin was indicated.

For your information I am furnishing you a link to the U. S. National Genealogical Society and the U.K. College of Arms. It is valuable information to know as some people get led astray.

Companies peddle these surname products on the internet because if they used the same selling methods by U. S. mail, they could be prosecuted for mail fraud.
