I was born in Poland and Polish language sources list these names for his children:
Władysław Wincenty Krasiński
Zygmunt Jerzy Krasiński
Maria Beatrycze Krasińska
Eliza Krasińska
I don't know where Graciosa comes from as it would not be used in Polish. Perhaps she was just given this nickname meaning graceful in other languages. Also the Polish forms of
Beatrix are Beatryks and
Beatrycze.
