Proof
Galadriel was born in
Valinor:
The Silmarillion, 'Of
Feanor':
"So the 3 kindreds were gathered in Valinor &
Melkor was chained....."
"In that time was born in Eldamar, in the house of the King.....the eldest of the sons of
Finwe....Curufinwe was his name, but by his mother he was called Feanor..."
So, if Galadriels father,
Finarfin wasn't born yet, she obviously wasn't either.
So, she was born in Valinor as she was 'eager to depart' upon hearing Feanor's words after the theft of
the Silmarils & death of his father.
On
Glorfindel (or Glorfindels), he (or they) could've been there on the journey to Valinor.
There's no proff either way, though & I personally would tend to doubt it.
Why?
Because note is made of 'The most noble' of the
Elves who heeded the
Valar's call.
If
Tolkien goes out of his way to bring in & mention Glorfindel at later points for his power & nobility, why wouldn't he mention it earlier?
And, on
Cirdan:
He was the Lord of the Teleri who did not depart ME & stayed at the Falas.
These Elves were 'original' or eldest (in terms of 'Awakening) as they were partakers of the great journey.
Would they chose or be led by a child of someone else?
Note that all the other Kindreds were led by those who were eldest (Olwe, Elwe, Finwe, Ingwe).
I don't know if this is clearly stated, but I believe it was Cirdan's 'fate' to dwell in ME longest of all the Eldar.
Remember 'He awaits the last ship' & 'Some say he still dwells there' (
the Grey Havens) even after the Departure of
Elrond & Galadriel.....
