Maria came to the von Trapp family in 1926 as a tutor for one of the children, Maria, who was recovering from scarlet fever, not as governess to all the children.
Maria did not marry Georg von Trapp because she was in love with him.
"I really and truly was not in love. I liked him but didn't love him. However, I loved the children, so in a way I really married the children.  . . . [B]y and by I learned to love him more than I have ever loved before or after."
There were 10, not 7 von Trapp children.

In the early 1940s the family settled in Stowe, Vermont, where they bought a farm. They ran a music camp on the property when they were not on tour.
Georg died in 1947 and was buried in the family cemetery on the property. Those who had applied for citizenship achieved it in 1948. The Trapp Family Lodge (which is still operating today) opened to guests in 1950.
