Y-Haplogroup: J-L24 (subclade J-Z7706) MtDNA: M5a2a1

Both of my maternal and paternal side are from the Habiganj District in the Sylhet Division of Bangladesh.

From my paternal side, we are Syeds, and from my maternal side, we are Choudhurys.

My paternal side descends from Syed Shah Nasiruddin (Shah Jalal’s companion) who was from Iraq, and from my family tree it seems to be that he is my 15th great-grandfather. [https://en.m.wikipedia.org/wiki/Syed_Nasiruddin]
