Lord of the Iron Hills
Lord of the Iron Hills was a title given to the rulers of the Iron Hills in eastern Wilderland. The only two known Dwarves to bear this title were Grór and his successor and grandson Dáin II Ironfoot. After Dáin became King of Durin's Folk and took up abode in Erebor, it is not known if anyone else then took up the title.
