Luedtke
A German surname most likely from a pet form of a personal name such as Ludwig or Liut.
The #9,061 most common surname in the United States (2010 Census) — about 1 in every 85,596 Americans shares it.
Etymology
Luedtke is a German surname formed from a diminutive or pet form of an older personal name, most likely one beginning with the element liut-, meaning "people" or "folk." It is often linked to names such as Ludwig, ultimately from Germanic roots meaning "famous" and "warrior," though exact local forms can vary. The ending -ke is a common North German diminutive, so the name likely began as a familiar nickname for the son or descendant of someone with that given name.
History
The surname is especially associated with northern German and Low German naming patterns, where diminutive surname forms are very common. In German-speaking areas it later became hereditary and was carried by emigrants to North America, where spellings with umlaut-like vowels were often adapted to plain Latin-letter forms such as Luedtke. In the United States it is now a relatively uncommon surname but still clearly recognizable as German in origin.
