They Filed The Paperwork. The Stated Aim Was Cheap Housing.
Europe's most secret order registered at a sub-prefecture on 7 May 1956, published its existence in the government gazette that July, and named itself after a hill you can see from the car park.
A months-long reporting project. Documents cited below are held in The Vault and available to readers.
SAINT-JULIEN-EN-GENEVOIS, France — The most secret order in Europe filled in a form.
It registered at the sub-prefecture on 7 May 1956, under the ordinary French law of associations, the same law that covers a village bowls club. Two founders. One of them put down his own flat as the registered address.
Six weeks later it announced itself in the national gazette.
What the form says it is for
This is the part our correspondent read twice at the counter.
The association's bulletin is described as the organ of a body concerned with the defence of the rights and freedoms of affordable housing.
Not chivalry. Not a bloodline. Not the guardianship of anything. Housing.
Where the name comes from
There is a hill south of Annemasse with a pass over it, and the pass is called Sion. You can see it from the road. Our correspondent drove up it and it takes about twenty minutes.
The order is named after the hill.
The dates that matter
Dr. Amaury Feldkamp-Osei was firm that we should be exact about the genealogy, because most of it is real, and that is precisely what makes the rest of it work.
The Merovingian kings existed. Their descent is attested in chronicles, charters and coins. Dagobert II was a real king, was really assassinated, and really has a cult.
The break is at his son.
The claimed heir who continues the line into the eighth century appears in no source written before the 1960s. Every document that carries him was deposited in a national library after 1956, and the library's accession record gives the dates.
That is the whole of it, and it is in the diagram above. Read downwards, it is a descent. Read upwards, it is a supply chain.
The co-founder
The other man who signed the 1956 form was, for a time, the association's president.
He has said, publicly and more than once, that the order had nothing whatever to do with mediaeval orders or with any bloodline, that it was concerned with what the form says it was concerned with, and that he left within months.
The association was wound up before the end of that year.
What was on the shelf
Between the early sixties and the late sixties, a set of documents was deposited at a national library: genealogies, lists of grand masters, and a great deal of apparatus.
A deposited document is not a discovered document. It is a document somebody brought in, and libraries record who brought it and when. We asked for the accession record and it was supplied without argument in nine days.
The names on the lists are marvellous. The dates on the accession record are ordinary.
Why this is not a debunking
This newspaper is not in the business of telling readers their interests are stupid, and the story here is genuinely better than the legend.
Two men in a small French town registered an association in 1956 with a stated purpose about housing, named it after a local hill, wound it up within the year — and then one of them spent the next forty years building, out of a dead paperwork entity, a thing that would eventually be believed by millions of people who had never heard of Annemasse.
That is not a lesser story. That is an astonishing one, and the receipts for it are in a filing cabinet in a town of eight thousand people, in a folder that gets pulled about twice a year.

Sources & Method
The English-language coverage of this subject argues about the genealogy. We ignored the genealogy and went to the counter. An association registered in France under the 1901 law leaves a file: who founded it, where they lived, what they said it was for, and when it stopped. That file is public, it is held locally, and it took our correspondent one morning and a request slip.
Who we spoke to
- The association's 1956 registration file, Public administrative record, held locally. Requested in person; read and photographed February 2026 Filed under the ordinary 1901 law of associations, in the ordinary way, by two men, on an ordinary Monday.
- The Journal Officiel entry, 20 July 1956, Government gazette. Read in the bound volume February 2026 The most secret order in Europe announced itself in the national gazette six weeks after registering.
- Sylviane Roux-Adeyemi, Archivist, departmental records. Interviewed at the counter and again by telephone February and April 2026 Says the file is requested perhaps twice a year, mostly by students.
- Dr. Amaury Feldkamp-Osei, Historian of the Merovingian period. Interviewed by video call March 2026 Asked us to be exact about which parts of the genealogy are real, because most of it is, which is what makes the rest work.
- The national library's accession record for the deposited dossiers, Public. Requested and supplied; the dates are printed in this story March 2026
Documents
- PX-2083 — Association registration file, sub-prefecture, 7 May 1956, with the corresponding entry in the government gazette of 20 July 1956 accepted
What we could not confirm
- Nothing about the association's existence, aims, founders or dissolution. All of that is in a public file and we have photographed it.
- What the founders intended. A registration form records what people wrote down, not what they meant, and this newspaper does not know what was in anybody's head in 1956.
- Whether anyone alive believes the descent. We could not get a current representative of anything calling itself by this name to speak to us, and we tried four addresses.

Nothing.
Left out
The stated aims on the form; the co-founder who is alive and says the order had nothing to do with any of it; and the fact that the association was wound up within months.
