"Matilda of Swabia (German: Mathilde von Schwaben; c. 988/989 – 29 July 1032), a member of the Conradine dynasty, was Duchess of Carinthia by her first marriage with Duke Conrad I and Duchess of Upper Lorraine by her second marriage to Duke Frederick II. She played an active role in promoting her son, Duke Conrad the Younger, as a candidate for the German throne in 1024 and to this end corresponded with King Mieszko II of Poland." - (en.wikipedia.org 01.11.2019)
