I am researching my great-grandmother. In a naturalization form on 1936-04-23, she listed her place and date of birth as Kolashine, Russia, 1888-11-09.
Where is Kolashine, Russia?
The only thing close to this that I've found is Kolasin, Montenegro, but this area has never been a part of Russia, so I guess that must not be the same place. Her husband was Polish (from the disputed Russian-Poland division area) so I thought perhaps it was in this same area, but I've searched google, ancestry.com, and oldmapsonline.org and found no results.
Following the advice on FamilyTree's wiki section for Russian Poland, I checked the relevant section of the 1877 Gazetteer of the Kingdom of Poland, but didn't find anything that looked like a match.
