Is it possible for Ida to marry John Lackland...
"Ida of Boulogne (c. 1160–1216) was suo jure Countess of Boulogne. She was the eldest daughter of Matthew of Alsace by Marie I, Countess of Boulogne. Her maternal grandparents were King Stephen of England and Matilda I of Boulogne. Her mother, a nun, had been abducted from a convent and forced into marriage by Matthew. As a consequence, her parents' marriage was rather controversial and was finally annulled in 1170. Her father continued to rule until his death in 1173, when she succeeded. Upon the advice of her uncle, Philip I, Count of Flanders, she married first in 1181, to Gerard of Guelders, but he died the same year. She next married Berthold IV, Duke of Zähringen, but he too died in 1186."
