Wandke House. Johann Traugott Wandke (1808-1870) immigrated from Prussia to nearby La Grange with his wife Christiane and two daughters, Karoline and Christiane, in 1855. About 1860 Johann and Christiane came to Round Top to live in the home of their daughter Karoline and her husband Zoellistin Pochmann. They built their own native stone home/workshop at this site about 1863. Johann was a skilled mechanic and cabinetmaker but is best known for the high-quality organs he crafted from native cedar for several churches in the area including Round Top's Bethlehem Lutheran Church.
