Dalmahoy is a Midlothian place-name that became a knightly surname, then a word for a wig, and then almost nothing at all.
The place is still on the map southwest of Ratho, with a country house, two golf courses and a steep green hill behind it. The surname is close to gone: the 1901 census of Scotland counted six people called Dalmahoy.
What Does Dalmahoy Mean in Gaelic?
The first element is dail, a haugh: the flat fertile ground beside water that a farmer notices first. It accounts for most Scottish places beginning Dal-.
The second element is a saint. W. J. Watson read the whole as Dail mo Thuae, "my Tua's meadow", from a holy man named Tua carrying the affectionate mo, "my", that Gaelic put in front of its saints. The modern Gaelic form of the place is Dail MoThua.
That reading carries a date with it. A dail compounded with a saint means Gaelic speakers were farming and worshipping here, not the Britons who held Lothian before them. The Gaelic surnames overview covers that shift, and Cramond shows it on another Edinburgh place-name.
The surname type is not in dispute. This is a name of ownership rather than trade, and our surname-origins guide sets out how that category is identified.
Who Were the Dalmahoys of That Ilk?
Small Lothian lairds who lasted an unusually long time. Henry de Dalmahoy appears in 1296, swearing to Edward I in the Ragman Roll. Adam de Dalmahoy took a charter in 1304, Thomas de Dalmahoy is named in one of 1408 from Robert, Duke of Albany, Sir Alexander de Dalmahoy in 1435, another Alexander on 8 March 1475, and William Dalmahoy in a grant of 1536.
That is eleven generations of quiet possession, and the house was good enough for royalty. James VI stopped at the old castle in April 1589 while hunting, and returned on 18 March 1598 with his brother-in-law the Duke of Holstein.
The high point was also the end. Charles II made John Dalmahoy of that Ilk a baronet of Nova Scotia on 2 December 1679; four held the title, three of them called Alexander, and it died with the fourth in 1800.
The land went first. By 1720 Dalmahoy belonged to George Dalrymple, younger son of the first Earl of Stair, whose family we follow in our piece on the Dalrymples of Stair. He hired William Adam, and the present Dalmahoy House was finished in 1725. Around 1750 it passed again, to James Douglas, 14th Earl of Morton, who swept away Adam's formal avenues and put a loch where they had been.
What Is on Dalmahoy Hill?
A fort that was old when the first Dalmahoy signed anything. Canmore records two phases of building on the twin summit to Kaimes Hill, the outer works enclosing a strip roughly 1,200 feet by up to 400, with a robbed wall about 3.6 meters thick still standing three meters high in places.
That larger circuit is taken as pre-Roman Iron Age. The small oval enclosure on the crown is the interesting one: a gold stud-cap a fifth of an inch across and fragments of metalworking molds came out of it, finds belonging to the post-Roman centuries. Somebody with gold and a bronzesmith was living up there while Lothian was still British, before Gaelic arrived to name the field below.
How Did Dalmahoy Become a Wig?
Quietly, and nobody has explained it. The Century Dictionary records dalmahoy as a common noun: "a kind of bushy bob-wig worn by tradesmen in the eighteenth century, especially by chemists."
The obvious guess is a London wigmaker or a conspicuous wearer of the name, and the family was certainly in the south. Thomas Dalmahoy, third son of Sir John Dalmahoy, was master of the horse to the second Duke of Hamilton, married the Duke's widow after Worcester, sat for Guildford from 1664 to 1679 and died in London in May 1682. Whether any of that put the name on a wig block is guesswork, and we would rather leave it as guesswork than invent a chain.
Is the Dalmahoy Surname Extinct in Scotland?
Effectively, yes. Six bearers in 1901 ranked it 18,852nd, and present-day distribution figures count roughly eight people worldwide, nearly all in England. What survives is the ground, the house, the hill and the word.
How Do You Trace a Dalmahoy Ancestor?
- Search Dalmahoy, Dalmahoye, Dalmahoi and Damahoy together. The last is a genuine contracted form, not a transcription slip.
- Begin in Ratho parish, Midlothian, whose registers start in 1682 for births and deaths and 1741 for marriages, late enough that the medieval lairds sit outside them.
- Use charters and sasines for anything earlier. A family this small leaves more in land records than in kirk registers.
- Widen to Edinburgh, then London and Surrey, where the younger sons went, and work any nineteenth-century line backward from a statutory certificate using our guide to Scotland's 1855 civil registration.
Frequently Asked Questions About the Dalmahoy Name
Where does the surname Dalmahoy come from?
It is territorial, taken from an estate in Midlothian southwest of Ratho. The place-name is Gaelic, best read as dail mo Thuae, the meadow of my Tua, a saint's dedication attached to a river haugh.
Are the Dalmahoys a clan?
No. Nobody has been chief of Dalmahoy, the name carries no clan organization, and no tartan is recognized for it. They were landed gentry holding one Midlothian estate for some four hundred years.
Is Dalmahoy House connected to the family today?
Only by name. It was built in 1725 for George Dalrymple, sold about 1750 to the Earl of Morton, and became a hotel with golf courses in 1927. No Dalmahoy has owned it in three hundred years.
