The House of Reznak is one of the ancient slaving families of Meereen.
A Dance with Dragons
Reznak mo Reznak is one of the current members of the House of Reznak. The House is supposedly less hostile to the rule of Daenerys Targaryen and Reznak serves as seneschal to Daenerys Targaryen  and later continues that position to King Hizdahr zo Loraq.
When several Meereenese ships join the blockade of Meereen, Skahaz mo Kandaq presents Daenerys Targaryen a list with the names of the Meereenese captains and which families they belong too. The House of Reznak was among the names.
