Mechtilda Püntener (née Zumbrunnen) was the daughter of Burkhard Zumbrunnen, probably born in the early 1300s. Mechtilda, the German version of the name Matilda, was a popular name among the German upper class in the 1200s and 1300s.
While sources agree that Mechtilda was the daughter of Burkhard Zumbrunnen, I believe this is some confusion in these sources and that she is the daughter of Burkhard Zumbrunnen who was a Knight in the Order of St. Lazarus, and the granddaughter (not the daughter) of Landammann Burkhard “Schüpfer” Zumbrunnen.
Mechtilda is the first known Zumbrunnen female, likely because of her husband: Johann Püntener. Johann lived on a piece of land called the Pünt, in the town of Seelisberg. Although Johann was apparently the third generation of the family to live on this land, he adopted the property as his name and became Johann Püntener, the first of a family that would go on to great prominence through the centuries in Uri, Switzerland.
