The encyclopaedia britanica, 2001 has given the following version about pre history of Ukraine.
“From prehistoric times, migration and settlement patterns in the territories of present-day Ukraine varied fundamentally along the lines of three geographic zones. The Black Sea coast was for centuries in the sphere of the contemporary Mediterranean maritime powers. The open steppe, funneling from the east across southern Ukraine and toward the mouth of the Danube, formed a natural gateway to Europe for successive waves of nomadic horsemen from Central Asia. And the mixed forest-steppe and forest belt of north-central and western Ukraine supported a sedentary agricultural population, linked by waterways to northern and central Europe. The marchlands of these zones were frequent areas of both military conflict and cultural transmission.Beginning in the 7th-6th centuries BC, numerous Greek colonies were founded on the northern coast of the Black Sea, in the Crimea, and along the Sea of Azov; these Hellenic outposts later came under the hegemony of the Roman Empire. During the 1st millennium BC the steppe hinterland was occupied successively by the Cimmerians, Scythians, and Sarmatians. These peoples, all of Iranian stock, maintained commercial and cultural relations with the Greek colonies.A period of great migrations began with the descent of the Goths from the Baltic region into Ukraine about AD 200. They displaced the Sarmatians, but their own power was broken about 375 by the invading Huns from the east, who were followed in the 5th-6th centuries by the Bulgars and Avars. Between the 7th and 9th centuries, the Ukrainian steppe formed part of the Turkic Khazar kaganate, a mercantile empire centred on the lower Volga River. Khazar control of the steppe was breached in the late 9th century by the Magyars. The Pechenegs, who followed, dominated much of southern Ukraine in the 10th and 11th centuries, and they were in turn succeeded by the Polovtsians (Cumans). Throughout this period of nomadic invasions, only a few of the Greek settlements in the Crimea, notably Chersonesus, maintained a precarious existence, relying on the support of the Byzantine Empire.”
I .Sara, a Canadian barrister and solicitor has pointed out that the recent excavations in the Ukraine and Crimea provide visible links of Jats and Scythians.
Cap. Dalip Singh Ahalawat has reported in an article published in Jat Samaj Patrika (Oct./Nov.1991) that Jats had ruled in Scythia and Central Asia. He has given a list of about 70 Jat gotras who have ruled over there. Details can be found in his book “Jat Viron ka Itihaas.”
According to a survey report by http://www.joshuaproject.net there are about 32000 Jats in Ukraine and their language is Jatali. If jats are there some of gotras pointed by Cap. Dalip Singh Ahalawat must be still there. One of ruler gotra pointed out by him is JAKHAR. I found on internet search that similar surname in Ukraine is ZAKHAROV. It is a matter of research if they are same or different. Surname Zakharov is masculine and Zakharova is faminine. Some names seem to be derived from Sanskrit such as, …Svetlana, Kupriyanova, Ushakova, Vakulenko, Veronika, Navratilova etc.
