As you know, just like the U.S., Germany, too, has always been made up of states. We're talking here about what was until 1945 the southwestern German state of Württemberg -- or if written without the "Umlaut" (two dots) over the "u", Wuerttemberg -- the capital of which was the city of Stuttgart. The people of Württemberg (Wuerttemberg) are known as Swabians (in German: Schwaben).
Following World War II, the state of Baden (capital: Karlsruhe), the state of Württemberg (Wuerttemberg), and the very small Prussian province of Hohenzollern (capital: Sigmaringen) combined to form today's new postwar southwestern German state of Baden-Württemberg (Baden-Wuerttemberg), with the city of Stuttgart as its capital.
"Bad" (pronounced: BAHT) is the German word for "bath". All officially recognized spas in Germany have "Bad" in front of their names -- for example, Bad Liebenzell.
Bad Liebenzell is located in the northern part of the Black Forest in the District (in German: Landkreis) of Calw. (A "Landkreis" is roughly equivalent to a county in a U.S. state.)
Church records are THE primary source of family information in German genealogy. If you visit your local Mormon Family History Center, you can obtain and view there on microfilm Bad Liebenzell's Evangelical Lutheran church records covering the years 1559 to 1926. They would give you all the information you would want about the Fuchs family.
