Library Catalog & Services

One of the many treasures of the German-Texan Heritage Society is the Charles G. Trenckmann Family Library. The library collection is named in honor of Charles Grover Trenckmann (1920-1988), a long-time member and benefactor of the German-Texan Heritage Society, and a German Texan himself, the grandson of William Andreas Trenckmann (1859-1935) of Bellville; the noted educator, publisher of Das Wochenblatt, and author of Die Lateiner am Possum Creek.

Who are we?

Part of the library’s collection is a set of hundreds of 20th and 21st Century books and self-publications ranging from family histories and genealogies to histories and overviews of Texas German music, art, culture, literature, and society. Some of our materials are the only copy in Texas. We are proud to announce that it is now possible to search this portion of the Trenkmann library catalog online.


To explore our library, please visit us at 507 East 10th Street, Austin, TX.

Our office is open Thursdays between 11 am - 4 pm or by appointment.
