Terrific research, Bilal Bhai. Bhanu Kaka, or Shamyomoy, was my father's classmate!
Had you noticed that of Benoy-Badal-Dinesh, all three were Bikrampur people? Two, Badal and Dinesh, were close relatives of ours. That is why the British discreetly posted my father to Chittagong, to liaise with XIV Army. His contemporaries, Khwaja Mohammad Kaisar and Taslimuddin Ahmed, got plum urban postings.
The percentage of Bikrampur folks, who have a long tradition of being highly educated are higher than other places in Bangladesh, because the area has always attracted top talent locally, being a seat of power and education in this area. Bikrampur was also the capital long ago of the Chandra dynasty in the turn of the 1000 AD Millenium; here are some other tidbits.

IMHO they also have a very proud upright tradition of righteous rebellions against oppressive rulers (latest being the British). They have also been very illustrious in the world stage. I know several good acquaintances from Bikrampur who have excelled in the education, arts and scientific fields. Here are a few entries of Bikrampur folks from Banglapedia online, which is way older than wikipedia,
