A French surname meaning “from the hill” or “from the mountain.”
The #5,177 most common surname in the United States (2010 Census) — about 1 in every 45,754 Americans shares it.
Etymology
Dumont is a French locational surname formed from du, meaning “of the,” and mont, “hill” or “mountain,” ultimately from Latin mons, “hill” or “mountain.” It was used for someone who lived by or came from a hill or elevated place. Historical dictionaries are in close agreement on this basic sense.
History
The name is well established in French and was carried into English-speaking countries by French families and later immigrants. It is one of several common French topographic surnames built with du + a landscape feature, alongside Dupont and Duparc. In English sources, it has sometimes been Anglicized or adapted in spelling, but the French form remains the standard.
