Culberson
A surname most likely formed from a personal name, meaning “son of Culbert” or a related ancestor’s name.
The #9,520 most common surname in the United States (2010 Census) — about 1 in every 90,409 Americans shares it.
Etymology
Culberson is best understood as an English patronymic surname built from a personal name such as Culbert or Colbert, with the ending -son meaning “son of.” The first element is likely a reduced or variant form of a Germanic name made up of elements meaning “bright” and “famous” or “bold,” though the exact pathway is not fully certain. In that sense, the surname originally identified someone as the child or descendant of a man called Culbert/Colbert.
History
The name appears to be a relatively uncommon English-style surname that later became established in the United States. Spellings with -son often stabilized in English-speaking records during the late medieval and early modern periods, especially as hereditary surnames became fixed. In American records, Culberson is best known through the political family of Charles A. Culberson, a U.S. senator from Texas.

Fun fact
