History & Origin

Mcadoo comes from the Gaelic surname 'Mac Conduibh', 'son of the black hound'. Its rare life as a given name is closely tied to William Gibbs McAdoo, President Wilson's son-in-law and Treasury Secretary, a very public figure during the First World War.

The name barely registered, given to only a couple dozen boys in total across a few years around 1918 before disappearing. A boy named Mcadoo then would be of a great-grandfather's generation; the name reads as a patriotic surname-name of a specific wartime moment rather than a lasting choice.

Did you know? Mcadoo's tiny American use around 1918 tracks the fame of William Gibbs McAdoo, the wartime Treasury Secretary.
