The previous heir-presumptive, Sir William Eure, a colonel in the Royalist army who died fighting at the Battle of Marston Moor, is sometimes wrongly stated to have succeeded as 6th Baron.
He was succeeded by his brother Ralph, Lord Eure, who joined with the Duke of Monmouth and others in petitioning Charles II against the Roman Catholics in 1680–1; and ― in the view of Mark Noble ― was one of those who had the courage to accuse James Duke of York of being a "popish" recusant.
Another of the brothers was Samual Eure, Esq., a colonel in the royal army, and a compounder upon that account for his estate.
Ewer was sent to conduct King Charles I from the Isle of Wight to Hurst Castle, named one of the commissioners to sit in judgment upon his sovereign (which he did, and signed the warrant for his execution); was one of those who were sent in 1649 to Ireland.
