The Sulgrave branch, however, was the most numerous and prosperous. From the mayor of Northampton were descended Sir William Washington, who married the half-sister of George Villiers, Duke of Buckingham; Sir Henry Washington, who made a desperate defense of Worcester against the forces of the Parliament in 1646; Lieutenant-Colonel James Washington, who fell at the siege of Pontefract, fighting for King Charles; another James, of a later time, who was implicated in Monmouth's rebellion, fled to Holland and became the progenitor of a flourishing and successful family, which has spread to Germany and there been ennobled; Sir Lawrence Washington, of Garsdon, whose grand-daughter married Robert Shirley, Baron Ferrers; and others of less note, but all men of property and standing. They seem to have been a successful, thrifty race, owning lands and estates, wise magistrates and good soldiers, marrying well, and increasing their wealth and strength from generation to generation. They were of Norman stock, knights and gentlemen in the full sense of the word before the French Revolution, and we can detect in them here and there a marked strain of the old Norse blood, carrying with it across the centuries the wild Berserker spirit which for centuries made the adventurous Northmen the terror of Europe. They were a strong race evidently, these Washingtons, whom we see now only by glimpses through the mists of time, not brilliant apparently, never winning the very highest fortune, having their failures and reverses no doubt, but on the whole prudent, bold men, always important in their several stations, ready to fight and ready to work, and as a rule successful in that which they set themselves to do.
