How is Luitgard von Istrien dead before her husband is born? This profile doesn't seem to be correct.
I think these are the trees that this profile is based off -

- one doesn't include Bertold II von Niddagau-Nüringen as her husband, or Luitgard von Nüringen as her daughter. Seems like her parents are unknown.
