I have recently been granted citizenship and now I am going to apply for British passport and I have below query,

As per passport application form, I have to give them following details of my grand parents as my parents were born abroad, but I don't have information as below,

1: names (known)
2: DOB (unknown)
3: Place of birth (unknown)
4: Date of marriage (unknown)

Can anyone please advise regarding above??

Thanks.

Thanks Jambo. Sorry I could not read this before posting as I was in bit rush.
Thank you very much

jambo's answer pretty much says it all. But to confirm, I spoke to someone recently over the phone and they reassured me (as per the IPS form guidance) that there is no need to put the grandparents' details in if one is applying on the basis of naturalisation, the only time grandparents' details are relevant if one is claiming citizenship by descent.
