Iain Umber son of Iain
Not to be confused with Iain Umber.
Iain Umber, son of Iain, was a member of House Umber, the line that holds Last Hearth in the far north of the Seven Kingdoms. He was the son of Iain Umber and Arwen Swann.
His name does not appear in the A Song of Ice and Fire novels: he is known only from the genealogies and histories of the great houses that accompany the television series.
