What happend to his wife and children?

i have been reading about siraj ud daulah's history which were all recorded by the british. i have reason to belive that alot of accounts are untrue and i found it hard to belive, i have only read one side of the story, whats the true other side?

i would like to read more on siraj ud daulah and currently i have limited source, how can i get hold of his full biography?

Are there any trace of blood line alive of nawabs family?

Were there any film's,(hindi or Bengali) books based on siraj's life story?
