From Tardis Wiki, the free Doctor Who reference
As far as I'm aware, Great Houses is a term which has only appeared in the Faction Paradox series. I'm pretty certain that Lungbarrow wasn't called a Great House in Lungbarrow. I know Cat's Cradle give a detailed description of Gallifreyan culture, so the answer may lie there, but certainly nothing from any BBC Book calls them Great Houses.
