Fredericksburg br/Gillespie County, Texas br/30 16.183' N 98 51.898' W br/511 E. Main Street br/br/Text: An evolution of pioneer building methods is evident in this home. The earliest part, built about 1845, is of fachwerk construction typical in early German houses. Later additions were of log and clapboard frame construction. Early area settlers Christian and Katharina Ressmann purchased the home in 1866 and in 1946 members of their family sold it to Hilmar and Christine Boos. The house remained in the Boos family until the 1970s.
