Actually the reer Shirdoon both clans visit the same grave is what I have heard and I saw
Beesha Xassan Sacad Muse Zubeyr Samaroon one time had a meeting with Beesha Xassan Sacad Muse Zubeyr Awal and they said they were related.
Apparently Makaahiil Dheere (Majority of Gadabursi) and Makaahiil Isaaq (Saad Musa) are also related. I've said this before but a JB from Gabiley has more in common with a Samaroon from Borama than he does with an HY from Erigavo or an HJ from Burco. JB and Samaroon are both agrarian land cultivators, which makes us unique among the Somali population which are for the most part pastoral nomads.
