Dunson
A surname most likely meaning “son of Dun” or “son of Dunn,” pointing to an ancestor with a name based on dark color or a short form of Donald/Duncan.
The #8,110 most common surname in the United States (2010 Census) — about 1 in every 75,525 Americans shares it.
Etymology
Dunson is best understood as a patronymic surname built on Dun or Dunn, with the ending -son meaning “son of.” The base name may refer to the Middle English and Scots word dun, meaning dark, swarthy, or brown, or it may be a shortened form of a personal name such as Dunn or Donn. In either case, the surname originally identified someone as the son or descendant of a man with that name.
History
The name is found chiefly in English-speaking countries, especially the United States, where it likely developed from older English and Scottish naming patterns. Many bearers may descend from families whose earlier surname forms were Dunn, Dun, or similar variants, with spelling stabilized later in records. As with many -son surnames, multiple unrelated families could have adopted the same form independently.

Fun fact
Because it is built from a short root plus -son, Dunson can look very straightforward, but it may hide several different family lines that arrived at the same spelling independently.
