You don't know the clan of "most of those people" because that's what happens when people stick their nose in something they know nothing about.

1st row: 
Muhammad Abdullah Hassan - Darood
Fatima Jibrell - Darood 
Mohamed Abdullahi Mohamed - Darood
Asli Hassan Abade - Darood
2nd row: 
Hanan Ibrahim - Isaaq
Hadraawi - Isaaq
Iman - Darood 
Sultan Yusuf Ali Kenadid - Darood
Aar Maanta - Darood
Sultan Mohamoud Ali Shire - Darood
Osman Yusuf Kenadid - Darood
Nuruddin Farah - Darood

I hope you know now. Not a single Hawiye person—who have contributed to Somaia the most and are the most dominant clan there military, politically and financially because someone has a grudge and has decided to exercise it through cheap propaganda.
