Schwenningen Kirchenbuch 1651-19??
These are the original church records -- across many volumes-- made contemporaneously throughout Schwenningen's history. They go back only as far as 1651. Church records prior to that-- if they existed-- were likely destroyed during the Thirty Years War (1613-1648). The original volumes are located at the Schwenningen Pfarramt. Direct access to these is limited to professionals approved by the Pfarramt. The Mormons microfilmed these records and these microfilms are available to the public in the U.S. (and to Mormons in Europe) through local FHL centers. Films numbered 1658743 through 1658748 [check].
Manfred Reinartz' Review of Inventuren-u. Teilungsbuch Schwenningen
The Inventuren-u. Teilungsbuch Schwenningen was compilation of records made shortly after the Thirty Years War (1618-1648) to help determine property ownership and inheritance. Reinartz reviewed these original records and summarized most, but not all, of what he found there in a book published abt. 1990 (928 pages). This compilation is available in his Haeuser Hoefe Hofstaetten book (see below).
Quellen zur Schwenninger Geschichte 890-1600, by Otto Benzing.

and published in this book.
Haeuser Hoefe Hofstaetten, by Manfred Reinartz, published in 1990, contains a compilation of a variety of alternative records (i.e., different than church records) -- mostly dealing with property and taxes-- from as far back as the 1300s through 1824. Excellent source for "bridging" the church records (which began 1651) to the pre-Thirty Years' War history.
A collection of property purchases during this time.

Otto Benzing Genealogy (Unsere Vorfahren in Schweningen und auf der Baar)
Produced in the 1930s [check] by the brothers Martin and Otto Benzing; this genealogy relied heavily on third party sources, not on the original church records; as a result it has been subsequently shown to include many errors. That said, a number of genealogists still use it as a primary source.
