Heinrich Diederichsen was born in Preits, Germany, the son of Detlef and Johanna Diederichsen. Prior to 1900 Heinrich married a woman named Sophie, and they later had three children; Heinrich Jr., Ellen, and Thornwald. From 1890 to 1920 Heinrich lived in Friedrichsorter, Germany, a small town in the northern German state of Holstein (near the border of modern-day Denmark). During this period Heinrich worked for the Freidrichsorter Technical Association (Friedrichsorter Techniker-Verein). During the 1920s Heinrich traveled to the United States and studied civil engineering in Portland, Oregon. After he completed his studies, he returned to Germany and worked as a draughtsman in the marine service.

In 1892 Anton immigrated to the United States and settled in Payette, Idaho. In January 1905 he married Millie Ferber in Sauk City, Wisconsin and they later had three children, Leona (1906) and twins Henry and Henriette (1912). Anton died December 31, 1948 in Payette, Idaho.
