Weidman
A surname of German origin, most likely meaning someone who lived by a wide or open place, or a variant of a related German name.
The #7,629 most common surname in the United States (2010 Census) — about 1 in every 70,976 Americans shares it.
Etymology
Weidman is generally understood as a German surname built from a Middle High German or regional German word for a wide, open, or meadow-like place, combined with the agentive element -man/-mann, meaning "man" or "person." In that sense, the name could originally have referred to someone who lived near an open stretch of land, or to a man associated with such a place. It may also sometimes reflect spelling variation from related German surnames such as Weidmann or Weideman.
History
The surname appears in German-speaking regions and was carried to North America by German immigrants and their descendants. In the United States, spellings without the doubled consonant are often the result of Anglicization or simplified recordkeeping. Because similar forms can arise from more than one German base word, some individual family lines may not share exactly the same origin.

Fun fact
The spelling with one -n is relatively common in English-language records, even when older German forms often keep the doubled -nn.
