According to a placard in the visitor center at Batsto, Julius Gerber married Katherine Reichert. She was born in Oberstein, Germany in 1862, and they were wed in June of 1883. Although they lived at Batsto for a time (supposedly in house #42), they later moved to Tylertown

I have also found what appears to be Julius' son, Louis, living in Tabernacle in 1920.
