Clashing Swords of Both the Cavalier and the Roundhead—Enemies

 

Tracing our family tree through the chaos of the English Civil War (1642–1651) reveals a fascinating, split-screen reality. Our family didn’t just experience this massive historical shift from one perspective—they were active players on both sides of the bloody conflict between King and Parliament.

While some of our ancestors were staunch Royalists ("Cavaliers") who fled England after the King’s defeat, others were ardent Puritans ("Roundheads") who actually traveled back to England from the colonies specifically to take up arms against the Crown.

Let's look at the incredible dual roles our 9th and 10th great-grandfathers played during this turbulent era.

1. The Cavalier Side: Colonel George Mason I (1629–1686)

Our 9th great-grandfather, Colonel George Mason I, was the absolute quintessential Virginia "Cavalier."

• The Clash at Worcester: George Mason was a staunch Royalist and a loyal officer in the army of King Charles I (and later Charles II). When the royal forces made their final, desperate stand against Oliver Cromwell’s Parliamentarian army at the Battle of Worcester in 1651, Mason was right there in the fray. The Royalists were utterly crushed, and Charles II famously had to hide in an oak tree to escape.
• The Flight to Virginia: Knowing that captured Royalist officers faced execution or forced indentured servitude in the colonies, George Mason fled the country. He boarded a ship bound for Virginia, a colony that remained deeply loyal to the Crown (earning it the nickname "The Old Dominion").
• The Frontier Legacy: Mason arrived in Virginia, used his resources to claim land along the Potomac River, and founded a powerful political dynasty. His fierce belief in individual liberty and deep distrust of unchecked government power was passed directly down to his great-grandson, George Mason IV, who penned the Virginia Declaration of Rights—the blueprint for our Bill of Rights.

2. The Roundhead Side: Captain George Denison (1618–1694)

While George Mason was fleeing Cromwell's army, our 10th great-grandfather, Captain George Denison, was doing the exact opposite—he was fighting for Cromwell.

• Returning to the Fight: George Denison had actually immigrated to Massachusetts as a boy in 1631. But when the English Civil War broke out in 1642, his deep Puritan convictions (and the heartbreaking death of his first wife, Bridget) prompted him to sail back across the Atlantic to join the parliamentary forces.
• The Battle of Marston Moor: Denison became a legendary cavalry officer under Oliver Cromwell. He was severely wounded at the pivotal Battle of Marston Moor in 1644, where the Roundheads decisively smashed the King's northern army. While recovering from his wounds at the home of a wealthy gentleman in Cork, Ireland, he fell in love with the daughter of the house, Ann Borodell.
• The New England Commander: They married in 1645 and sailed back to New England, where George used his elite military training to become the premier defender of the Connecticut frontier, leading troops in King Philip's War and building the historic Denison Homestead in Mystic, Connecticut, which still stands today.

📜 A House Divided: How the English Civil War Forged Our American Roots

Celebrating America 250

To understand the character of early America, you have to understand the fire in which it was forged. Long before our ancestors picked up muskets against King George III in 1775, their grandfathers were fighting a brutal, bloody civil war back in England—a war that split our own family tree right down the middle.

On one side of the campfire stands my 9th great-grandfather, Colonel George Mason I. He was a proud Cavalier—a loyal defender of the King. When Oliver Cromwell’s Puritan army crushed the Royalists at the Battle of Worcester in 1651, Mason found himself a wanted man. He fled across the Atlantic to the safe haven of Virginia, carrying with him a aristocratic pride, a love for the land, and a deep-seated fury against government tyranny that he would pass down to his great-grandson, Founding Father George Mason IV.

But on the other side of the fire stands my 10th great-grandfather, Captain George Denison. He was the ultimate Roundhead. Though he had already settled safely in Massachusetts, when the war broke out, his fierce Puritan faith called him back to England to fight against the King. He rode with Cromwell’s cavalry, bled on the battlefield of Marston Moor, and won the heart of his Irish bride, Ann Borodell, while recovering from his wounds.

When Denison returned to New England, he brought Cromwell’s strict iron discipline with him, using it to defend and map out the rugged wilderness of early Connecticut.

Think about the incredible irony of that. In the 1640s and 50s, George Mason and George Denison were mortal enemies. If they had crossed paths on an English battlefield, they would have drawn swords to cut each other down. One fought for the Crown; the other fought to overthrow it.

Yet, generations later, their independent, battle-tested bloodlines traveled down the long wagon trails of history, surviving the wilderness, crossing the prairies, and eventually blending together in the heartland of America to produce my grandparents.

As we look at America’s 250th birthday, I realize that our nation's unique spirit didn't come from just one way of thinking. It was hammered out by the clashing swords of both the Cavalier and the Roundhead—enemies in the Old World, but bound together as ancestors in the New World.
