But your link says she "was the daughter and heir of King Henry I of England" and "married Henry V, Holy Roman Emperor"!

[Samuel_Michon]

Ah yes, I see your point now. A couple of centuries after the first Henry V, there’s another Henry V, born in England.

Of course, there are plenty of kings and child brides to choose from. How about Richard II of England, who married Isabella of Valois when she was 6 years old?
