The Scottish surnames of Clan Hamilton have spread across the globe. From South Lanarkshire to the United States, Canada, Australia, and New Zealand, this powerful Lowland clan left a deep mark on history. If Hamilton, Bannatyne, or Cadzow appears in your family tree, you carry the blood of Scotland’s most ambitious noble house.
The Hamiltons were once the most powerful family in Scotland after the royal Clan Stewart. They held castles, commanded armies, and nearly took the throne itself. This is the story of Clan Hamilton — and the surnames that connect you to it.
Where Does the Hamilton Name Come From?
The name Hamilton comes from a place in England. The Norman knight Walter fitz Gilbert came from Hambledon, a village in what is now Leicestershire. The name Hambledon comes from the Old English words hamel (bare or blunt) and dun (hill). It means “the bare hill.”
Walter fitz Gilbert arrived in Scotland in the late 1200s. His lands were first in Renfrewshire. But it was his choice of allies in Scotland’s wars that shaped everything that came next.
He chose Robert the Bruce. And that choice changed his family’s fortunes forever.
Scottish Surnames of Clan Hamilton
Clan Hamilton had several septs — smaller families who owed loyalty to the Hamilton chief. If your surname appears below, Clan Hamilton may be part of your Scottish story.
Hamilton
The name Hamilton is one of the most common in Scotland today. It spread widely across Ireland, North America, Australia, and New Zealand. Its Gaelic form is Hamaltún, found mainly in Ulster-Scots records for families who carried the name west in the 17th century.
Cadzow
Cadzow was the original name for the Hamilton seat in Lanarkshire. It was a local family name before Walter fitz Gilbert arrived. When the Hamiltons took the lands, many Cadzow families became a sept of the clan. The name still lives on in Cadzow Street and Cadzow Castle in the town of Hamilton.
Bannatyne and Ballantyne
The Bannatyne family were long allied with Clan Hamilton. The name comes from the Gaelic Baile an Teine, meaning “homestead of fire.” Richard Bannatyne served as secretary to John Knox, the Scottish reformer. Today the name survives in several forms: Bannatyne, Ballantyne, and Ballantine all share the same Gaelic root.
MacGibbon
MacGibbon means “son of Gibbon,” a pet form of the name Gilbert. The Hamilton line began with Walter fitz Gilbert, so the MacGibbon connection makes historic sense. This name appeared mainly in Renfrewshire and Lanarkshire — the heart of Hamilton country.
Brown
Brown is one of the most common surnames in Scotland, but many Brown families in Lanarkshire and Renfrewshire had direct ties to Clan Hamilton. If your Brown ancestors came from South Lanarkshire, it is worth exploring the Hamilton connection in your research.
Other surnames sometimes linked to Hamilton include Sorby and MacHamish. If you are tracing your roots, organisations like the Clan Hamilton Society maintain detailed genealogical records and DNA projects to help you find your line.
The Hamilton Tartan
The Hamilton tartan is one of Scotland’s boldest. The base is red, crossed by broad blue stripes with thin white lines. It is a striking, confident pattern — right for a family that spent centuries at the heart of Scottish power.
There are hunting and dress versions too. The Hamilton Hunting tartan uses green as its base. The Dress version keeps the red but softens the colours for formal wear. All three are worn by Hamilton descendants around the world today.
The clan motto is simply: “Through.”
It is one of the shortest clan mottoes in Scotland. But it says everything about how the Hamiltons lived. They pushed through rivals. They pushed through crises. And they pushed their way to the very edge of the Scottish throne.

A Brief History of Clan Hamilton
Walter Fitz-Gilbert and Robert the Bruce
The Hamilton story begins in the chaos of the Wars of Scottish Independence. Walter fitz Gilbert first appears in the records around 1294. He held Bothwell Castle on behalf of the English — a sign of where his loyalties once lay.
But Walter switched sides. He backed Robert the Bruce. After Bruce’s great victory at Bannockburn in 1314, Walter was rewarded with the barony of Cadzow in Lanarkshire. Those lands became the foundation of the Hamilton dynasty.
Like other great Lowland clans, from Clan Douglas in the Borders to the rival Lowland houses, the Hamiltons built their power in the rich agricultural lands south of the Highland line.
A Royal Marriage and a Claim to the Throne
The Hamiltons’ greatest moment came in 1474. James Hamilton, 1st Lord Hamilton, married Princess Mary Stewart. She was the daughter of King James II of Scotland.
That marriage placed the Hamiltons directly in line for the throne. For the next century, they were never far from the top of Scottish politics. When there was no clear heir, a Hamilton was often next in line.
James Hamilton, 2nd Earl of Arran, became regent of Scotland in 1542. He ran the country while the infant Mary Queen of Scots was too young to rule. Later he helped arrange the marriage of Mary to Francis, the French Dauphin. The King of France made him Duke of Châtellerault as a reward.
The Isle of Arran Connection
The Hamiltons became Earls of Arran in the 15th century. They made Brodick Castle on the Isle of Arran their island home. The castle dates back to the 13th century, but the Hamiltons shaped it into the structure that stands today.
Arran became a Hamilton stronghold. From there they watched over the Firth of Clyde and controlled the western sea routes into Scotland. Brodick Castle is now in the care of the National Trust for Scotland and is open to visitors year round.
Hamilton Palace and Chatelherault
At the height of their power, the Dukes of Hamilton built one of the largest private palaces in Europe. Hamilton Palace stood near the town of Hamilton in South Lanarkshire. It held a priceless art collection. European royalty came to visit. It was a symbol of how far a Norman knight’s descendants had come.
But coal mining beneath the town caused the ground to shift. The palace began to sink. By the early 20th century, it was beyond repair. Workers demolished it between 1922 and 1932. Almost nothing remains today.
The hunting lodge known as Chatelherault still stands, however. It sits in Chatelherault Country Park on the edge of Hamilton. You can visit it today. The park also holds the ruins of Cadzow Castle — the ancient heart of Hamilton lands.
Alexander Hamilton: Scotland’s Gift to America
One of the most famous Hamiltons in history was American. Alexander Hamilton was a Founding Father of the United States. He helped write the US Constitution. He became the first Secretary of the Treasury. His face appears on the $10 bill.
His Scottish roots run deep. His grandfather, Alexander Hamilton of Grange, was an Ayrshire laird. That family came from the Cambuskeith branch of Clan Hamilton — a cadet line of the main clan. So when you see Hamilton’s portrait, you are looking at a man with genuine Lowland Scottish blood.
He is not alone. Hamiltons appear across the history of North America, the Caribbean, and the British Empire. The name carried weight wherever Scottish emigrants went.
Hamilton Emigration and the Scottish Diaspora
Hamiltons left Scotland in waves. The 17th century saw many move to Ulster as part of the Plantation of Ulster. From Ulster, many families then crossed the Atlantic to North America.
Others sailed directly from Scottish ports. Ships carrying Hamilton emigrants docked at Boston, New York, and Philadelphia. Many settled in Pennsylvania, Virginia, and the Carolinas. A large community formed in Ohio.
Later waves went further. Australia and New Zealand drew Scottish settlers all through the 19th century. Hamilton, Waikato, is New Zealand’s fourth-largest city. It was named after Captain John Hamilton of the Royal Navy, who died at the Battle of Gate Pā in 1864. His clan roots traced back to Scotland.
Today the Clan Hamilton Society links descendants around the world. They gather at Highland Games from North Carolina to Ontario to New South Wales. If you are tracing these roots, our guide to tracing your Scottish ancestry will help you find your line.
Where to Visit Hamilton Country in Scotland
Bothwell Castle
Bothwell Castle sits above the River Clyde in South Lanarkshire. It is one of the largest and best-kept medieval castles in Scotland. Walter fitz Gilbert once held it for the English — and then chose to hand it to Bruce. The Hamiltons held power here for generations after.
The castle is run by Historic Environment Scotland and is open to the public. The great round donjon tower still dominates the site. It is a powerful place to stand and think about the Hamilton story.
Chatelherault Country Park
Chatelherault Country Park is just south of the town of Hamilton. The hunting lodge at its heart was built for the Dukes of Hamilton in the 18th century. It has been restored and is open to visitors. Ancient white cattle roam the gorge below. The ruins of Cadzow Castle stand nearby. There is nowhere quite like it in Scotland.
Hamilton Mausoleum
The Hamilton Mausoleum stands in Strathclyde Country Park, near the town of Hamilton. The Dukes of Hamilton built it as a private burial chapel. It holds the record for the longest echo of any building in the world — a full 15 seconds when a door slams shut. It is a Category A listed building and open for guided tours.
Brodick Castle, Isle of Arran
Brodick Castle is the most iconic Hamilton site. It sits on the east coast of Arran, looking out over Brodick Bay. The Hamiltons shaped it over 500 years of ownership. It passed to the National Trust for Scotland in 1958. Today you can tour the castle, walk the walled gardens, and hike up to the summit of Goatfell.

Lennoxlove House, East Lothian
After Hamilton Palace was demolished, the family moved to Lennoxlove House near Haddington in East Lothian. It is still the home of the Duke of Hamilton. The house holds portraits, furniture, and artefacts from the Hamilton collection — including a death mask of Mary Queen of Scots. Lennoxlove opens to visitors on selected dates throughout the year.
