There is indeed several appropriate names in the Serpent Kingdom supplement, but they are scattered over the whole book. There is not a single table compiling a list of Yuan-ti names. Then, while the book is nice, it is useful only if you plan to run a campaign which arching plot is centered around Yuan-ti and the like. However, the original poster (and whoever is interested in the subject) may prefer to get some actual name suggestion, not the advice to buy yet another book. That said, here is a list of names I came up with / compiled a while ago:
Male names: Akris, Athanos, Daziss, Ischyros, Kress, Mariss, Oshphim, Salethar, Sarek, Selanu, Sellak, Shanastar, Shiraal, Silass, Thaxos, Tithian, Xamres, Xutan, Zorai, Zureth.
Female names: Ashissa, Caress, Daïsha, Deryssa, Ibisis, Ivaniss, Lalassu, Nassirah, Nessa, Nysia, Pyrrha, Saaveed, Sadai, Salah, Shallia, Suehra, Thassia, Veeshis, Ydriss, Zivlil.
