Genesis 10:3 - Matthew Poole's English Annotations on the Holy Bible

Ashkenaz, whose seed possessed Pontus and Bithynia, and the neighbouring parts, from whom they took the names of the lake and haven called Ascanius, and the sea called Axenus, or Euxinus. Riphath is called Diphath, 1 Chronicles 1:6; the letters Daleth and Resh being oft interchanged, as we shall see in other instances. His posterity dwelled in or near Pontus and Bithynia, where Mela and Pliny and Solinus place the Riphaei, or Riphaces, and the Paphlagonians, who were anciently called Piphataei. Togarmah, whose posterity are joined with Gomer s; see Ezekiel 27:14, Ezekiel 38:6; and were, as some think, the Phrygians and Galatians, and of them the Gauls and Germans; or, as others, the Armenians, and of them the Turks.
