Poole on 1 Chronicles 1:38-42: The Sons of Seir
Verse 38: And the (Gen. 36:20) sons of Seir; Lotan, and Shobal, and Zibeon, and Anah, and Dishon, and Ezer, and Dishan.
[The sons of Seir] This is not Esau, but a Horite of another nation, Genesis 36:20, whose genealogy he describes, so that the descent of Timna, the mother of Amalek, might be understood (Mariana, Lapide, similarly Menochius, Tirinus).
The sons of Seir; one of another nation, prince of the Horims; whose genealogy is here described, because of that affinity which was contracted between his and Esau’s posterity; and those who were not united and incorporated with them were destroyed by them. See Deuteronomy 2:12.
Verse 39: And the sons of Lotan; Hori, and Homam (or, Heman, Gen. 36:22): and Timna was Lotan’s sister.
Verse 40: The sons of Shobal; Alian (or, Alvan, Gen. 36:23), and Manahath, and Ebal, Shephi (or, Shepho, Gen. 36:23), and Onam. And the sons of Zibeon; Aiah, and Anah.
[Alian] Hebrew: עַלְיָן/Alyan, who in Genesis 36:23 is called עַלְוָן/Alvan: but י/y and ו/v are easily exchanged on account of their similarity (Malvenda).
[Shephi, שְׁפִי] Who in Genesis 36:23 is called שְׁפוֹ/Shepho (Malvenda).
Verse 41: The sons of Anah; (Gen. 36:25) Dishon. And the sons of Dishon; Amram (or, Hemdan, Gen. 36:26), and Eshban, and Ithran, and Cheran.
[Hamram] Hebrew: חַמְרָן/Chamran; who in Genesis 36:26 is חֶמְדָּן/ Chemdan, on account of the similarity of the ר/r and the ד/d (Malvenda).
Verse 42: The sons of Ezer; Bilhan, and Zavan, and Jakan (or, Akan, Gen. 36:27). The sons of Dishan; Uz, and Aran.
[Jakan] Hebrew: יַעֲקָן/Yaakan; who in Genesis 36:27 is called עֲקָן/ Akan (Malvenda).
 Hebrew: וּבְנֵ֣י שֵׂעִ֔יר לוֹטָ֥ן וְשׁוֹבָ֖ל וְצִבְע֣וֹן וַֽעֲנָ֑ה וְדִישֹׁ֥ן וְאֵ֖צֶר וְדִישָֽׁן׃  Hebrew: וּבְנֵ֥י לוֹטָ֖ן חֹרִ֣י וְהוֹמָ֑ם וַאֲח֥וֹת לוֹטָ֖ן תִּמְנָֽע׃  Genesis 36:22: “And the children of Lotan were Hori and Hemam (וְהֵימָם); and Lotan’s sister was Timna.”  Hebrew: בְּנֵ֣י שׁוֹבָ֔ל עַלְיָ֧ן וּמָנַ֛חַת וְעֵיבָ֖ל שְׁפִ֣י וְאוֹנָ֑ם ס וּבְנֵ֥י צִבְע֖וֹן אַיָּ֥ה וַעֲנָֽה׃  Genesis 36:23: “And the children of Shobal were these; Alvan (עַלְוָן), and Manahath, and Ebal, Shepho (שְׁפוֹ), and Onam.”  Hebrew: בְּנֵ֥י עֲנָ֖ה דִּישׁ֑וֹן ס וּבְנֵ֣י דִישׁ֔וֹן חַמְרָ֥ן וְאֶשְׁבָּ֖ן וְיִתְרָ֥ן וּכְרָֽן׃  Genesis 36:26: “And these are the children of Dishon; Hemdan (חֶמְדָּן), and Eshban, and Ithran, and Cheran.”  Hebrew: בְּֽנֵי־אֵ֔צֶר בִּלְהָ֥ן וְזַעֲוָ֖ן יַעֲקָ֑ן בְּנֵ֥י דִישׁ֖וֹן ע֥וּץ וַאֲרָֽן׃  Genesis 36:27: “The children of Ezer are these; Bilhan, and Zaavan, and Akan (וַעֲקָן).”
