Doerr
A German surname often representing the spelling Doer or Dör, sometimes linked to a word meaning a spear or to German vowel simplification.
The #5,817 most common surname in the United States (2010 Census) — about 1 in every 51,960 Americans shares it.
Etymology
The surname Doerr is usually explained as a German spelling of a name with an umlaut vowel, often normalized as Doer or Dör. In older scholarship, some writers also connected it with Old Norse doerr, glossed as “spear,” but that explanation is not certain. Because the historical sources here are brief and partly incidental, the safest summary is that Doerr reflects German surname spelling and may preserve an older nickname or personal-name element related to a spear.
History
German surnames of this type often entered English-speaking records through immigration and were then simplified in spelling. In American usage, Doerr is typically treated as a German surname, and the form with double -e- reflects an anglicized way of writing an umlauted vowel. The historical material supplied does not give a single secure origin story, so the name’s deeper derivation remains debated.

Fun fact
In older surname studies, Doerr was sometimes grouped with forms like Derr and Dorr because German umlaut spellings were often flattened in English records.
From the historical record
“me that this name, as well as our own Torr and yc ToRRY, is not from another root, probably Old Norse doerr, spear. Thor does not occur in the directory of Copenhagen, though the patronymic Thorsen is common. Grimm thinks that Thor is only a contracted form of Anglo-Saxon thuner, Old Norse thonar,”
