Aircraft and Baron Edmond de Marçay
This is more a tangle ball of yarn than a designations list. Some sources describe Edmond de Marçay as an aeronautical genius, others as an enthusiast with a pile of money. De Marçay did go through a string of partner engineers.
The first was a Dutchman, J. Kluijtmans (variously misspelled as 'Kluytmann', 'Kluytmans', or 'Kluytemans'). In 1906, Kluijtmans had designed the first airship in the Netherlands but this project had faltered due to lack of interest and financial resources. De Marçay was able to solve both problems. Together, they designed a radical dirigible (tested as a scaled-down airship built by Paul Leprince). Kluitjtmans went on to design heavier-than-air machines on his own but, AFAIK, no fixed-wing aircraft for de Marçay.
The first de Marçay heavier-than-air aircraft was designed with Emile Moonen. The 1911 de Marçay-Moonen monoplane was the first to feature folding wings for transport and storage. Together, de Marçay and Moonen had filed UK Patent 18,661 "Improvements in and relating to Aeroplanes and other Machines" in Oct 1909, describing the folding wings.
In 1912, Edmond de Marcay and Emile Moonen also proposed an oblique wing design for the first time. [1] "The idea was to vary sweep of oblique wings for landing in sideslip." [2]

[2] "Conceptual Assessment of an Oblique Flying Wing Aircraft including Controls and Trim Characteristics", Ryan W. Plumley (Masters thesis), 2008, pg.3
From 1916-to-1918, Anonyme d'Etudes et de Construction Aéronautique Edmond de Marçay in Bordeaux built 400 x Spad VII C1s but there is no sign of special designations applied.
Later designs are assigned exclusively to de Marçay. But, in L'Aeronautique 166, mention is made of a M. Botalli associated with the engineering of a monoplane tourer designed by de Marçay (presumably the de Marçay T-2). And a long-term association between de Marçay and Botalli is implied.

Établissements d'Edmond de Marçay
It is not clear to me what company name (if any) de Marçay's early aviation efforts fell under. Later, the Construction Aéronautique de Marçay was formed in Bordeaux (or, more formally, the Société Anonyme d'Etudes et de Construction Aéronautiques Edmond De Marçay -- shortened to S.A.E.C.A de Marçay or Construction Aéronautique Edmond De Marçay). In web searches, the Établissements Edmond de Marçay & Cie (Paris) will pop up. This was an unrelated de Marçay firm which made Anzani-powered Cyclecars from 1920-to-1923.
De Marçay Aircraft Designations
The earliest de Marçay aircraft are simply described (without real suggestive of a formal naming). Examples are the de Marçay-Kluytmans Dirigeable (aka dirigeable Kluytmans de Marçay) or Monoplan de Marçay-Moonen. As these early designs were built in very small numbers, perhaps it was thought that no name or designation was needed.
An exception was the 1912 de Marçay-Moonen L'Abeille ('Bee') ... although 'abeille' may also have been an early useage for light aircraft akin to 'avionnette'.
After WWI, de Marçay types were given numbers. Only four numbers are known ('3' is missing) but there is a numeral repetition with the 1919 de Marçay 2 C1 sesquiplane fighter and the 1920 de Marçay T-2 monoplane tourer.
I have also seen the de Marçay 2 C1 fighter described as the 'Type C'. I assume this to be a generic term -- 'C' being for 'Chasse'.
At this stage, I run out of de Marçay projects. So, was de Marçay an enthusiast financier. Or was he an amateur aircraft designer in need of engineering assistance? Can anyone help untangle the naming/designation mess? Can anyone add any other de Marçay aircraft designs?
