Some recent research has established one probable descending branch of Aharon through several Gaonim of Sura and then proceeding through Yehudah HaCohen (Sir Leontin), teacher of Me'or HaGolah, into many current sub-branches. To view details of this work please see the Supplemental Data to this paper: https://www.academia.edu/43340967/ (in file #2). Persons in any yDNA group within the S17446 sub-tree (a very large set of branches) are part of this yDNA lineage. If you are not sure of your haplogroup placement please post your haplogroup classification here and I will attempt to locate the placement.
