Eidson
An English-language surname that likely began as a patronymic form meaning “son of Eid” or a variant of a similar personal name.
The #7,585 most common surname in the United States (2010 Census) — about 1 in every 70,474 Americans shares it.
Etymology
Eidson is most likely an English surname built with the common northern English and Scottish surname ending -son, meaning “son of.” The first element is probably a shortened or altered personal name, often explained as a variant of an older given name such as Ead, Edith, or another name beginning with Eid-/Ed- in dialect spelling. In many cases like this, the exact source name is uncertain because the spelling has shifted over time.
History
The surname is most likely from a localized English patronymic that later spread in North America through migration. Spellings with -son often became fixed surnames by the late medieval or early modern period, and later American records sometimes standardized variant forms such as Eidson, Edison, and Edson separately. The name is relatively uncommon today and is most visible in the United States.

Fun fact
Because the first element is unclear, Eidson is one of those surnames where the ending is easy to read but the original given name behind it may never be recoverable with certainty.
