Renamed Szczecinek, West Pomeranian Voivodeship, Poland
'New Stettin' = Neustettin, Regierungsbezirk Koslin, Pommern (distinct from Stettin itself, 145km away). Row's own citation (Meyers Vol.2 p.301) already confirms this and that the stored pin (53.7078/16.6992) matches Wikidata Q848999 (modern Szczecinek) almost exactly. The row's aliasNames '(now Szczecin...)' is a separate, likely-mistaken earlier edit (Szczecin is a different, larger city) -- flagged for a human, not touched here.
