Re: Where is Kristelowka/Kristelowha? #russia
It's very likely that her last name was Yerusalimskiy, from Russian word Yerusalim (Jerusalem). This names was fairly common in the Kiev governorate, including in the Uman uezd (location of the Kristinovka village, as suggested by Giannis). The scans of the 1897 census for Kristinovka are not yet available, but hopefully soon.
You should probably check periodically for their availability at this URL: https://uk.wikisource.org/wiki/Архіви/ДАКО/384/12. According to the index, the documents for this village are found in files #130-135.
