I read that the name or parts of the company was years later changed to Gnome or LeRhône, but the engine did not bear this name yet.
A the time there was a lot of experimenting and exchanging knowledge among aircraft and engine designers, collaboration and split ups going on, along with the founding of other/new companies.

There was the german Gnom, french Gnome, LeRhône, Gnome et Rhône (Société des Moteurs Gnome et Rhône), Gnome LeRhône (all with sometimes wrong designation), then Clerget, Bentley and so on, but apart from the initial german Gnom one-cylinder they were all a bit later.
When the french companies developed the small Gnom engine into usable aircraft engines they now had to get a patent from them to create their own Oberursel and Siemens-Halske rotary engines.

I saw that there is a lot of wrong information in Wikipedia..
