Etymology
Edmondson is an English patronymic formed from the personal name Edmund plus the suffix -son, meaning “son of Edmund.” The given name Edmund goes back to Old English Ēadmund, combining elements meaning “wealth, fortune” and “protection.” In medieval records the surname appears in several spellings, including Edmondson and Edmundson, reflecting normal variation in the writing of names.
History
The name is well attested in England by the late 14th century, with examples in records from 1379. Later surname dictionaries note it as a regular expanded form of Edmund and Edmunds, rather than a separate origin. The distribution in later sources points especially to northern English use, including Lancashire and Yorkshire.
