Sahal,
From reer Diini I am bah-Xawaadle. From bah-Xawaadle, I am reer Siyaad.
Before we started migrating enmass to Garbahaaray and Buurdhuubo districts in the last 80 years , the principal nucleus of reer Siyaad was ceelasha Qalqalooc, Ulasan, Laba Baar, and Baar Magoog between Shiilaabo and Hiiraan.
This is by the famous Italian explorer Enricco Cerruli when he traveled in the area then and was inspired to illustrate my reer Siyaad Diini Ugaas controlling the area
My grandpa told me when he was a very small kid there, they would host a lot of Somali herders from different clans who needed water.
A good chunk was Hawaadle and other Hawiye (Cayr most prominent among Hawiye).
As was custom, we had a diya-paying system in our Xeer in case conflict arose between the groups hosted in the water well.
The Aw-Qutub of Sheekhaal and the reer Aw-Xassan were guaranteed by us (they paid mag with us meaning they were under our protection). My grandpa told me the Aw-Qutub even had a saying "Sideeda reer Siyaad, anaa ku sagaal ah" and the reer Aw-Xassan had loyalty towards us that was like iron which is why how we became very close through intermarriage which still exists (for example Fahad Yaasiin is married to my reer Siyaad eedo...Idaajaa's sister).
Cayr gauranteed all other Hiraab (few Saleebaans really) and had a "Hawiye" diya agreement with Baadicadde and Gaaljecel (no other Hawiye there really) and this diya covered the ocassional Murusade or something.
Xawaadle among other clans like Dir/Qubeys were part of no groups which tribally made sense.
In fact the majority of the conflicts we had to settle was between you as Xawaadle and they as the Hawiye diya paying group.
Xawaadle was not part of this Hawiye system and never ever participated in a Hawiye shir. So sxb I am quite familiar with the time the "qaramayn" occurred and the politics that led to it (formation of Hiiraan as a region by the Italians, scramble for tribal political alliances in the corrupt 60's, insecurity surrounding Xawaadle not genealogically part of any major clan, civil war strategies, etc).
P.S. I don't put any stock in "voting" in the 60's. Who voted and where? Corruption, impunity, illiteracy, they didn't even have written language and Somali wasn't even the national language. Did they go into a booth and have general Somali population vote in Italian?
No. I am telling you as the former Somali Central Bank governor said in a talk I went to, a group of boys would be rounded up and spend all night and day check off thousands of ballots where they were told to check off.
Voila! All of a sudden a town voted! Waa quraafaad
