Can we draw the following hypothesis from the context?

Context:

Kisimul Castle (Scottish Gaelic: "Caisteal Chiosmuil" ) and also known as Kiessimul Castle, is a small medieval castle located on a small island off Castlebay, Barra, in the Outer Hebrides, Scotland. It gets its name from the Gaelic "ciosamul" meaning "castle island".

Hypothesis: Most Scottish people call it Caisteal Chiosmuil rather than Kisimul Castle
It's impossible to say
