To the right is Narain's version of the genealogy of these kings. Below are family trees of the Euthydemid, Eucratid, and Menanderid dynasties. The Greek connection to the Qin emperors of China is shown below, and with this connection, the ancient kings of Persia, Greece, and China, oddly enough, are all related.

The most surprising discovery I made in my research is that the "Hu" (胡) son of Qinshi Huangdi, Hu Hai (胡亥 229–207 BC), most likely was the son of a princess offered by the Greco-Bactrians during that alliance (epigamia). The name of Hu Hai's mother was "the Hu Princess" (Hu Ji 胡姬), and information about her is surprisingly sparse in the Chinese historical records. Normally, when Hu Hai came to the throne, his mother would have received the posthumous title (fenghao 封号) of "empress dowager" (Huang Taihou 皇太后), and women in that position were usually very active in politics. But she did not, and shows no such activity. This is strange to the point of being abnormal in the ruling class of the Qin. The reason is probably that she was a princess of the Euthydemid family, and, in the eyes of the Qin aristocracy, a "Hu," or a "foreigner." That is why she was not completely included in the royal dynastic system. The "Hu Princess" bore Hu Hai in 229 BC. Euthydemos must had made an alliance with the "king of Qin," who
