I learnt through this article (in French) that there used to be a strong colony of Francoprovençal / Arpitan speakers in Ukraine, up until the early 20th century!
The reason for this oddity takes us back to 1822, when Russian Czar Alexander I had a lot Swiss people settle in Bessarabia (Western Ukraine, Moldova, Northeastern Romania) to cultivate vineyards
Ten years earlier, Russia had conquered these lands from the Ottoman empire. Alexander I's private tutor was Swiss himself and encouraged the emperor to bring over Swiss expertise to make wine and populate a newly-acquired territory
The article highlights a crucial fact regarding the transmission of language; because these settlers enjoyed a relatively broad degree of autonomy, they were not under immediate pressure to abandon their language and assimilate into Ukraine
A Swiss swan hunter in 1913 on the shores of the Black Sea heard what he identified as "patois vaudois" - meaning Francoprovençal. He expected to see a fellow Swiss but these Francoprovençal words were uttered by a mujik (Russian мужи́к "peasant"). The man worked as a domestic for one of the settlers family
The Swiss presence lasted until 1940, when the Bessarabia region came under the USSR's sway and the state abolished private property and the Swiss went back to Switzerland
