Who married Henry VII of Brzeg?

Henry VII with a Scar also known as the Courageous or of Brzeg (Polish: Henryk VII z Blizną, Waleczny or brzeski; 1343/45 – 11 July 1399), was a Duke of Brzeg (Brieg) since 1361 (as co-regent of his father until 1398) and ruler of Niemcza since 1395.

He was the eldest son of Louis I the Fair, Duke of Brzeg by his wife Agnes, daughter of Henry IV of Głogów-Żagań. The death of his younger brother Wenceslaus in 1358 left him as the only male heir of his father.

In the almost contemporary "Kronice Legnickiej" Henry VII was assigned the term "z Blizną" (with a scar), which was adopted later by historians as a nickname. This term was maybe the result of the wounds on his face obtained under unknown circumstances (ca. 1373), where apparently he was near to death.

Margaret of Masovia Polish: Małgorzata (before 1358 – 14 May 1388/4 April 1396) was Duchess of Pomerania and Brzeg, by her marriages to Casimir IV, Duke of Pomerania and then to Henry VII of Brzeg. She was a member of the House of Piast.

Margaret was a daughter of Siemowit III of Masovia and his wife Euphemia of Opawa. Her paternal grandparents were Trojden I of Masovia and his wife Maria, daughter of Yuri I of Galicia and Euphemia of Kuyavia.
