[3] The elder son Dafydd, who succeeded as 7th Baron, had the half of Hendwr centred on the caput of the Barony.

The family, like their kinsmen, were Royalists during the English Civil War and Lt. Nathanael Jones, fought at the Battle of Marston Moor, leading a company of men from Llandrillo.

Descendants of Nathanael's younger brother, John Jones of Ty Ucha (d.1705) continued to hold land in the barony of Hendwr until it was all sold in 1840s and the family moved to Cheshire.

[13] As descendants of Owain Brogyntyn, they bear the 'Black Lion' of Powys on their escutcheon and the crest A tower argent (symbolising Hendwr) which was confirmed in a grant of arms by Randle Holme, deputy herald for Chester and North Wales at the College of Arms.

[2] Their arms hang in the hall of Jesus College, Oxford where several members of the family were educated.
