It was sad, some of the things that happened to Kate. She deserved better luck than that. Her husband lived until he was 98 (2003) and I think that the other children are still alive. One of the daughters was living in her old house.
Kate wrote a book "Cloud Over Arnhem" and AIUI she appeared in
Theirs is the Glory (1946) (aka
Men of Arnhem)
Two things to do in that area.
Walk from the drop zones to the west of Oosterbeek, near Wolfheeze, into Arnhem - and then tried to imagine doing it heavily laden and under fire.
Second, have a look at the river by Oosterbeek and imagine trying to swim it or even to try to cross it in a small boat under fire.
