Ahmed Mohamed Mohamoud
Mohamoud was born in 1938 in the mideastern town of Burco, situated in what was then the former British Somaliland protectorate. Nicknamed "Silanyo", he hails from the Habar Jeclo (Aaden Madoobe) clan of the Isaaq. Ahmed M. Mohamoud Silanyo is the third child of four. His father was a merchant marine, so the family lived a half-nomadic, half-settled lifestyle. He was the only child in the family to attend a formal education, fostered by an uncle who was a strong influence on his early life. His brothers followed their father's footsteps as merchant marines. He is Muslim.
