Then there was this- 'The duo collected saliva samples from 39 of the infamous dictator’s living relatives, including a great-nephew, Alexander Stuart-Houston, who lives in New York, and an Austrian cousin identified only as “Norbert H.” Tests were then conducted to reveal the samples’ principal haplogroups, which are sets of chromosomes that geneticists use to define specific populations.
Writing in the Flemish-language magazine Knack, Mulders reported that the relatives’ most dominant haplogroup, known as E1b1b, is rare in Western Europeans but common among North Africans, and particularly the Berber tribes of Morocco, Algeria, Libya and Tunisia. It is also one of the major founding lineages of the Jewish population, present in 18 to 20 percent of Ashkenazi Jews and 8.6 to 30 percent of Sephardic Jews.
