Chi ha sposato Federico I di Lorena?

Federico I di Lorena (circa 1155 – 7 aprile 1206) fu Duca di Lorena per circa tre mesi, nel 1206.

Wierzchoslawa Ludmilla of Greater Poland (Polish: Wierzchosława Ludmiła Mieszkówna; b. bef. 1153 – d. bef. 1223), was a Polish princess member of the House of Piast, by marriage Lady of Bitsch and during 1205-1206 Duchess of Lorraine.

She was the second daughter and fourth child of Mieszko III the Old, Duke of Greater Poland and since 1173 High Duke of Poland, by his first wife Elisabeth, daughter of King Béla II of Hungary. Her name was probably given after High Duchess Viacheslava of Novgorod, wife of Bolesław IV the Curly, the ruling High Duke of Poland; with this gesture, Duke Mieszko III maybe showed an expression of warming relations between him and his brother the High Duke.
