Almost perfect, except for the last:
Der Eigentum der Mädchen ist...
should be
Das Eigentum der Mädchen ist...
Just wanted to correct that because I did not want you and /u/yorkshire_lass to memorize it like that.
Sometimes I think Twain was right about us.
But then again I had a couple of years of French and Latin, and my inflections in both are substantially worse than yours. In addition to that I have had quite a few more years of English in school and at two universities and I am still not at the level of a native speaker. This might indicate that languages besides German are also hard (the alternative would be that you are more intelligent than I am, but you will not catch me admitting that).
