mismatch in father's name

Respected sir/madam,
My name is Arpan Dey.My father's name in my documents is Asok kumar Dey. But the documents of my father contain the name Asoke kumar Dey. As my father is deceased, is it possible to make an affidavit stating that Arpan Dey's father Asok kumar Dey and Asoke kumar Dey are the same person?
*Only my adhaar card have the name Asoke kumar Dey as my father's name.
Please suggest to me what I need to do. It is needed for document verification for a job.
Thanking you,
Arpan Dey
