I do see two Freida Zilberman in Khotin uezd, born one in 1856 and a second in 1855. They seems lived not in Khotin, but in towns in that same uezd (county), one family in town of Brichany and second in town of Lipkany. Sometimes our ancestors, when asking where they are from, will give a name of a large town or a center of county or province.
If you know the names of Freida parents, that might help here.
