children of a dead British citizen

[Aksa]

My Late Mother was a British Citizen, she married a Pakistani man and settled in Pakistan, after having two kids , they both separated but not legally. My father left the country and since then we don't have any contact with him. My mother raised us on her own, she was a gynecologist. we used to go to UK to meet my grand parents (late) but on my mother's passport. She died in 2009. Now is it possible for her children to apply for immigration? If yes what is the process???
