Larry W. Boelman USAF Retired in the About section you state that she married "Duke Herman of Swabia" on or around 1190, but the husband she is connected to on Geni is Hermann II who dies in 1103.
I remember the story that is in Margaret's About Me but i cannot remember who the story is about.
Googling "Duchess Margaret of Austria" does not turn up anyone that can be a match for this person, who ever she is she is definitely not the wife of Herman II, duke of Swabia.
I have tried yet again to resolve who this person may be without any success, certainly she is not the wife of Hermann II, duke of Swabia.
My best guess is that you might have meant this woman, although the facts do not match exactly:
https://en.wikipedia.org/wiki/Margaret_of_Austria,_Queen_of_Bohemia
Here is a copy of the information from the profiles About, the profile contains no other data:
Margaret was one of the first Margravines to Royalty when she became a Queen consort to the King of Germany. His untimely death left her in charge for no more than 10 years before another King was crowned and she became the Duchess consort of the Duke of Austria.
Her political prowess and skill manifested themselves again when her husband dies and she must manage the affairs of Austria until a new Prince is found.
Still a powerful figure, with experience and a reputation for leadershp un-parralled in the annals of the times, she finally becomes Queen of all Bohemia.
Around or before 1190, she married Duke Henry of Swabia and passes the throne to her eldest son.
