According to Fred Guweddeko, a researcher at Makerere University, Amin was the son of Andreas Nyabire (1889–1976). Nyabire, a member of the Kakwa ethnic group, converted from Roman Catholicism to Islam in 1910 and changed his name to Amin Dada. He named his first-born son after himself. Abandoned by his father at a young age, Idi Amin grew up with his mother's family in a rural farming town in north-western Uganda. Guweddeko states that Amin's mother was Assa Aatte (1904–1970), an ethnic Lugbara and a traditional herbalist who treated members of Buganda royalty, among others. Some sources have also described Amin as being of mixed Kakwa-Nubian origin.
