We are a Jewish family that immigrated from Pereyaslav, Ukraine in the 1890s. Every Zlatkovski I have come across feels that it is rare name and all are related. One Mikhail Zlatkovskiy found a history to a Baron Henryk Zlatkovski in the 16th century. Do you know of any Jewish heritage to your family? Judging from the distribution of Zlatkovski families, they all originated in the area around now-Belarus, and several branches settled easterly across the Pale, and one group as far as Uzbekistan. There is a parallel story of the name Da Costa applying to the family. Any light you can share will be welcome. Our Zlatkovskis settled in Minnesota.
