The Nestle family tree began with three brothers (thus the three young birds in the nest being fed by their mother on the family coat of arms) from Mindersbach, called Hans, Heinrich, and Samuel Nestlin. The father of these three sons was born circa 1495. Hans, the eldest, was born in 1520 and had a son with the same name, who later became mayor of Nagold. His son Ulrich was a barber and his fifth son was the first glazier in the family. For over five generations, this profession was passed down from father to son. Additionally, the Nestles provided a number of mayors for the boroughs of Dornstetten, Freudenstadt, Nagold, and Sulz am Neckar.
