A few questions - AN form

[Ajenta83]

Dear members,
I’ve just started to fill in the application form; and came across the first point that’s confusing me.
1.7 /1.8
I’m a EEA national, originally from Sri Lanka (obtained nationality through naturalisation when I was 2; when both my parents did). My name on my birth certificate at that time was slightly different from what it is when I obtained the EEA nationality. This had to with; how my parents decided to short the names for confinience purposes; and in Sri lanka it’s common to use the fathers first name as the family name. Long story short: I have not been known on any official documents by those names since I obtained the EEA nationality (nor in the specific EEA country or UK).
The name was for example:
First names: Arunya Charlinyffy; Surname: Kavipillai (Fathers first name: Francis; Surname :Kavipillai); after naturalisation my name has become: Arunya Charliny with the surname: Francis).
Do I have to inform about this? The only reason why I’m thinking of not doing is; is I believe I have to provide proof of this; which is going to be a pain to obtain. And as evidence/proof of identity I am providing my licence; and all the passports (expired ones) etc as well; which are all in the same name. I’m planning not to include my birth certificate as proof of identity (as this would only trigger confusion, I believe).
Your opinion and advice is highly appreciated.

Dear members,
The time has come that I am actually filling in an AN form . I’m an EEA national, who obtained PR somewhere back in 2014. I have a few questions whilst filling in the form, and I’m hoping you are able to advise me please:

1.3 If you are an EEA national, a Swiss national or a family member of an EEA or Swiss national you should read pages 10 to 11 of the Booklet AN.

Is this the date you’ve obtained PR? If so; so I have requested information from SAR. Where the outcome date is put down as 8/5/2014 (same as the issue date on my PR). Is this the date that I fill in?

p.s not sure if I'm allowed to create a new topic or whether I should have merged my questions with the other topics?

Please keep ALL questions on the same application in a single topic. Thanks.

Apologies CR001 - I'll stick to one topic.
