1 Chronicles 1:40  (King James Version)
The sons of Shobal; Alian, and Manahath, and Ebal, Shephi, and Onam. And the sons of Zibeon; Aiah, and Anah.

Both these variations are also caused by the mutation of [Ywd] {yood} and [Vv] {wav}; the former being written
[Alvn ,] Alvan, and
[Alyn ,] Alian; and the latter,
[Shephw ,] Shepho, and
[Shepy ,] Shephi. Genesis 36:23

Alvan, Shepho
The difference here is only in the translation; the original being uniformly [Ayh ,] Aiyah.
Genesis 36:24
