Somalis do this too. I have several half cadaan or half something else relatives on 23andme from places like the United States, Canada and the UK. Some of them even messaged me asking if I could possibly help them find their aabo. Sad stuff. One girl I saw was from California and half Yahud. I should get friendly with her. Might have a future in Hollyweird.
This is the reason why Im scared of doing a DNA test, Im afraid of my few ilbax adeers and their shenanigans. I could have an army of half cadaan kids.
