Minsk

Minsk is a city in the European Alliance on Earth and was the capital city of the former nation of Belarus.

Sergey and Helena Rozhenko were residents of Minsk and for some amount of time raised their son Nikolai and their foster son Worf there. When Alexander Rozhenko went to Earth to live with the Rozhenkos in 2367, it is likely that they lived in Minsk then as well.

In 2375 when Miles O'Brien was preparing to move back to Earth, Worf insisted that O'Brien consider Minsk for his new home. (DS9 novelization: What You Leave Behind)

In 2379 Worf was forced to return to Earth to report the fact that Emperor Kahless was a hologram and to deliver the demands of the Klingon High Council. Before returning to Qo'noS, he traveled to Minsk to visit his foster parents. (TNG novel: A Time for War, A Time for Peace)
