Бобровничане plural Бобровничанка female Бобровничанин male However most people have never heard most of these words and even less the derivatives. When we need to name the inhabitants of an area with a rare or complex name. We DO NOT user derivatives or demonyms. Instead we reword to "проживающий в Бобровнике" or similar. This is the only way it works.

They decide themselves how to be called :) I'd say: male - бобровничанин female - бобровничанка plural - бобровничане As for бобровские, бобровцы or бобровчане - why to eliminate the suffix -ник?

villagers, most likely would have called "Бобровские", less likely "Бобровцы", and "Бобровчане" if it would be sity.

Yes, male and female residents of a place called Бобровник. Not a plant.
