Hallo,
in surch of some historical fragments I found your homepage with hints of Eduard Aetheling and his wife Agatha. But please let me correcting you: Agatha was not a Braunschweig or Brunswick, she was the daugther of Steven 1st of Hungary and his wife Giselle of Bavaria. Her brother was Imre (Emmerich) the saint.
In Hungary it´s well known, that Agatha of Hungary (Ágota) was married to Eduard Aetheling.
Greetings from Germany
