When William Duke of Normandy wanted to marry Matilda of Flanders, it is said she took the marriage proposal as an insult. William was an illegitimate bastard who luckily got his father’s role as duke while she was a high-born grand-daughter of the French monarch King Robert II. Luckily for her she did marry William as he later invaded and won the English throne. So as William became king, she obvioulsly became Queen of England.
