I thought you couldn't claim to be a fictitious ethnicity. Well, guess what, I was proven wrong today.
Well, Owen Glyndwr in post #71 just mentioned Silesians - an ethnicity equally "fictitious" as Macedonians.
Actually, Silesians are even more "fictitious" than Macedonians, because nobody heard of them (or of their language) during the 16th century:
"(...) Zwei Volksstämme, die sich nicht nur nach ihren Wohnsitzen, sondern auch nach ihren Sitten scheiden, bewohnen es; den nach Westen und Süden gelegenen Theil nehmen die Deutschen ein, den Theil nach Osten und Norden zu die Polenö beide trennt als eine ganz sichere Grenze die Oder von der Neißemündung ab, sodaß auch in den Städten diesseits die deutsche, jenseits die polnische Sprach vorherrscht. Man erkennt zwischen beiden Völkern einen starken Gegensatz. (...)"

Barthel Stein, "Descriptio Tocius Silesie et Civitatis Regie Vratislaviensis", published in 1513.
Which translates to English:
"(...) It [Silesia] is inhabited by two ethnic groups [Volksstämme], distinct from each other not only in terms of territories they occupy, but also in terms of customs; Western and Southern parts are inhabited by Germans, while Eastern and Northern parts are inhabited by Poles, they are divided by a safe boundary roughly along the Oder River starting from the outlet of the Neisse River in such a way, that also in cities on one side of the river we can hear German speech, while in cities on the other side by contrast we can hear Polish speech. Between these two peoples there are strong differences. (...)"
By contrast, Slavic-speaking Macedonians were already known under this name at that time, or at least their Slavic language was
Macedonice:
