Isabella and the Cape

In 1308 Philip the fourth of france was trying to ease tensions with england by arranging for his own daughter Isabella to be married to prince edward. No one imagined that this wedding would actually lead to an english king that would have a claim to the french throne. By happy accident since the days of hu capet or capet i think is how the french would Ape? Ape? Maybe It's a ET so i'm really leaning towards the like a the cape.
