Fillery Family History
Fillery Surname Meaning
From Anglo-Norman French fiz or fil (de) le rei ‘son of the king’ generally taken as implying that the bearer was a bastard son of the king. However, McKinley notes that in late 13th-century Sussex, one bearer of this is a customary tenant, suggesting that in his case it must have been used either as a (mocking?) nickname or as a fancy way of denoting the son of someone surnamed le Ray ‘the king’.
Compare Kingson and see Ray and King both of which occurred in medieval Sussex.
