form 325-A Grandparent's DOB unknown?

[ek_Desi]

I am filling out 325-A for my father. He does not know the date of birth of his parents (my grand parents). What should be done in this situation?

Also, what to write for City and Country of residence? They have passed away.

Hi. If your grandparents' birthdate is unknown, write unknown. Since they have passed away, write deceased.
