Idda von Bramberg was a daughter of an illustrious family in Lucerne, Switzerland. She married Walter Zumbrunnen, who became the Landammann of Uri. She was likely born in the late 1300s.
Walter and Idda owned land in both Schattdorf (presumably inherited from Walter’s mother Hemma Fürst) and in Attinghausen. Idda and Walter made a major donation to the St. Andreas Church in Attinghausen to establish a sort of religious-charitable foundation (the exact nature is unclear to me). They are thus recorded in the Necrology of the St. Andreas Church.
They had at least three children: two sons both named Johann and a daughter, Margarita. The oldest Johann followed in his father’s footsteps as Landammann of Uri.

Idda von Bramberg entry at FamilySearch.org (free registration required). Her birth year is estimated as 1415. That’s 20 years younger than the estimate for her husband and I don’t know the basis for thinking there’s such a large gap, although it’s certainly not impossible.
