We are hailing from Mahinagar area of West Bengal(India).The area is located near to Kolkata(Calcutta).Since there are many lineages of Bose family from West Bengal,it might help in narrowing down the search.I have been able to trace about four generations of my forefathers,but I have not come across the names you mention.More details from your side my help.
Thanks.
