Еврейские корни

Hello all - I am researching my Faivishevsky and Gardashnik families. I have had a high success in locating birth, death, marriages through neizhen family search scanned documents indexed there back to ~1850 and many, many relatives have been uncovered. Where else should i look? We know that Faivishevsky were Kohan. I'm looking for other documents to search. Thank you in advance!

Я исследую семьи Файвишевский и Гардашник. Мне удалось обнаружить записи о рождении, браке и смерти в отсканированных документах по Нежину. Там есть индекс записей до ~ 1850 года. Мне удалось определить много родственников.
Где еще я могу посмотреть? Мы знаем, что Файвишевский был Коганом. Я ищу другие источники поиска.

Thank you! Likely a relative. I could not find a way to contact him by email.

smhapp1, I have something interesting for you!
One of your relatives was converted from Judaism to Orthodoxy, there is a record of it in Kyiv archive, because it took part in one of its churches.
Goda Leibovna (patronym) Faivishevsky from Nezhin (Chernigov gubernia) changed her name to Anne on the 9th of december 1900. She was 22 years old. Do you recognize her?
