Disputatio:Smolenscum
In case there are several variants of latinisation, none of which is much more widespread than the others, let us choose the variant, which is closer to the native name. (Creating redirect links from the rest variants of Latin names, if necessary.) The problem is that sometimes a better variant of latinisation is found after the article is already created. (That is, e.g., the situation with Smolensk - Smolska - Smolsca - Smolenscum.)
