We are in a process to Wikify book by H. W. Bellew titled -
An Inquiry Into the Ethnography of Afghanistan/Page 26-50 which will be of great help in understanding Jat clans.
I quote from this book page-36:
Strabo says,
"Most of the
Scythians, beginning from the
Hyrkanian Sea, are called
Dahai Skuthai, and those more to the east
Massagetai and
Sakai; the rest have the common appellation of
Skythians, but each separate tribe has its peculiar name. The best known tribes are those who deprived the Greeks of Baktriana, the
Arioi,
Pasianoi,
Tokharoi, and
Sakarauloi, who came from the country beyond the
Jaxartes, opposite the
Sakai and
Sogdianoi, and which country was also occupied by Sakai. Some tribes of the
Dahai are surnamed
Aparnoi, some
Xanthioi, others
Pissuroi. The Aparnoi approach nearest to
Hyrkania and the Caspian Sea ; the others extend as far as the country opposite to Aria."
