Schlabach
A German surname most likely referring to a place by a brook or stream, with spelling influenced by dialect and later Americanization.
The #7,382 most common surname in the United States (2010 Census) — about 1 in every 68,397 Americans shares it.
Etymology
The surname is German in form and appears to be built from dialectal elements equivalent to Schlab- plus bach, the common German word for “brook” or “stream.” In onomastic sources, it is treated alongside other German surnames ending in -bach, suggesting a place-based origin rather than a straightforward occupational one. The exact first element is not fully certain from the excerpts alone, but the overall shape strongly points to a locational surname meaning someone from, or living by, a particular brook-side place.
History
The name shows up in German-American surname lists from the early 1900s, where it is grouped with other German names and compared with anglicized spellings such as “Slay back.” That kind of rendering suggests the pronunciation was unfamiliar to English speakers and was sometimes respelled phonetically in the United States. The surname is now especially associated with American bearers of German ancestry.

Fun fact
