Who were the oldest elves in the third age?

Who were the oldest elves in the third age?
We do not have exact birth dates for everyone, but it seems that the following elves were the oldest.
Galadriel: Galadriel was born in the Years of the Trees in Valinor, making her one of the oldest and most powerful Elves in Middle-earth. She is of the royal house of the Noldor, being the granddaughter of Finwë, the High King of the Noldor. Galadriel participated in the rebellion of the Noldor against the Valar and later ruled the realm of Lothlórien in Middle-earth alongside her husband, Celeborn.
Círdan the Shipwright: Círdan is another ancient Elf who dwells in Middle-earth during the Third Age. He is renowned for his shipbuilding skills and is the lord of the Grey Havens, the Elven port on the western shores of Middle-earth.
Celeborn: Celeborn, the husband of Galadriel, is also among the oldest Elves still alive in the Third Age. He is of the Sindar, the Grey Elves, who dwelled in Beleriand during the First Age. Celeborn's origins trace back to the ancient days of Middle-earth, and he played a significant role in Elven history alongside Galadriel.
Thranduil: Thranduil is the Elvenking of the Woodland Realm in the northern part of Mirkwood. He is of Sindarin descent and is one of the oldest Elves known to still dwell in Middle-earth during the Third Age. While his exact age is not specified, he is likely among the elder Elves who remember the fading of the Elder Days and the rising of the Sun.
Glorfindel: Glorfindel is an Elf-lord who dwelt in Gondolin during the First Age and later returned to Middle-earth in the Second Age. He is known for his valor and wisdom, particularly his role in the Fall of Gondolin. While not explicitly stated, Glorfindel is considered to be one of the oldest Elves still present in Middle-earth during the Third Age.

Of these I think it is safe to say Cirdan was the oldest, and could have been second or third generation since the awakening of the elves. Galadriel would definitely be second oldest.
