Royalties due to lineage?

I've known for years now that I am the great-great neice of former vice president, Hubert Humphrey (who served beside Lyndon B. Johnson. Although proud of this, I never gave it much thought.....until this last election when someone asked me if I thought my family was entitled to anything monetary, seeing as how their are tons of properties and memorials and bridges named after his legacy....Could this be true?
