Fredericksburg br/Gillespie County, Texas br/30 16.660' N 98 52.388' W br/205 W. Austin Street. br/br/Text: August and Johanne Hennersdorf migrated to Fredericksburg from Prussia in 1855. In the early 1900s they constructed this frame and limestone residence for their family. Evidence indicates the floor joists under the frame portion of the home may be the octagonal wooden columns from Fredericksburg's original vereins Kirche, which had been dismantled in 1896. Members of the Hennersdorf family owned the property for ninety years.
