OOPS!! SORRY, I made Gertrude the daughter of herself > Her full name was "Gertrude Margrethe Andersdatter". She was the daughter of, "Anders Mortensen" and "Karen Kirstine Sorensdatter". With these Danish names, the "Datter" added to the name of a female means, "daughter of". For instance, Sorensdatter" would be, daughter of Soren.
