Their seat was the castle of Harrenhal, which was granted to them after the extinction of House Harroway. However, the Strongs also died out, like all the Houses to hold Harrenhal, and the castle was passed on to House Lothston.
In the books
There have been a number of historical Strongs mentioned in the books. One was Ser Lucamore Strong known as "Lucamore the Lusty". He was a knight of the Kingsguard during the reign of Jaehaerys I who broke the Kingsguard vows of chastity by secretly marrying three women and fathering sixteen children. His sworn brothers discovered this and informed the king, who then had the Kingsguard geld Lucamore and sent to the Wall to join the Night's Watch.
Other notable Strongs were Lord Larys Strong, Lord of Harrenhal, who served as Master of Whisperers under King Viserys I and King Aegon II, and Ser Harwin Strong, lover of Rhaenyra Targaryen and rumored father of her first three children.
Although House Strong is considered extinct, during the timespan of the events described in A Song of Ice and Fire novels there are several known characters whose surname is Strong:
- Duncan Strong, an exile serving with the Golden Company.
- Denys Strong, an exile serving with the Golden Company.
- Ser Robert Strong, a knight of the Kingsguard under Tommen I Baratheon. Presumed to be the reanimated Gregor Clegane.
It is uncertain whether the abovementioned Duncan and Denys actually belong to House Strong, because in the free companies a man can call himself whatever he chooses; in the case of Robert Strong, it is undoubtedly an assumed name.
