There are some tribes that were called the AW clans and some of them joined other tribes like Sheekhal part of Hawiye, Leelkase(ex Xer) part of Daarood, Faqi part of Dir
Somali tribes are divided into two types; Waranle and wadaad, The Wadaads were allowed to live in the land of the Waranle fighting tribes so they spread out in different places like Hiiraan, Mudug, Bari, Buurxakabo, Luuq etc.
What tribes did leelkase and sheekhaal join also do both those clans exist in hiiraan burhakaba luuq etc
Layl kase genetic results have so far come under this unique E3B clad -->
https://www.yfull.com/tree/E-Y163949/
This clad has so far grouped together the majority of the Layl Kase, Marehan, Dhulbahante, Warsangeli, Jidwaaq groups in Ethiopia, aspects of Ogaden, and aspects of Majerten (Wabeneye).
It seems to be an interesting clad implicating what if anythingy has been reflected by the oral genealogical lineage called "Darod"
To my knowledge the only individual results from those identified lineage groups above who have not come under that clad are individuals who have self-identified themseves as artisanally privileged or craftsmen. Essentially individuals whose identities are more multifaceted and progressive than the socially exclusivist and limiting constraint historically applied to these things.
So Layl Kase Xer and, for example, Dir Surre Xer do not have their occupation of being Xer necessarily informing much about this aspect concerning lineage.
