Family where bumbling yahoos rule (5,5)

I believe the answer is:

royal house

'family' is the definition.
(I know that family can be written as royal house)

'bumbling yahoos rule' is the wordplay.
'bumbling' indicates an anagram.
'yahoos'+'rule'='yahoosrule'
'yahoosrule' anagrammed gives 'ROYAL HOUSE'.

'where' acts as a link.

I've seen this clue in The Guardian.
