Charles Ellicott Commentary 1 Chronicles 1:30

"Mishma, and Dumah, Massa, Hadad, and Tema," — 1 Chronicles 1:30 (ASV)

Dumah. —Isaiah 21:11, as a name of Edom. There is still a locality bearing this name, “Duma the Rocky,” on the borders of the Syrian desert and Arabia.

Hadad. — The right reading here and in Genesis.

Tema. — Taimâ’u, in the north of the Arabian desert. The Septuagint confuses it with Teman. (Assyrian Têmâl’a).
