Onkel Franz wanted to marry Hedy Engemann and was engaged to her in the late 1920's.

He never married. After his retirement (he worked many years for the Alcoa Aluminium Company in Northern New Jersey), he returned to Germany, where he lived in Starnberg am See in Southern Germany for many years together with his cousin on his father's side, Paula Richter. Franz wished to be buried in the village of his birth. Paula Richter is also buried there.
