Which year was Ash (the real Ash, called Echo) born?

Hello THE100 community,

I start to understand how ALL that works!

It is important to know at which year the real Ash (called Echo) is born?

We know a part of the story about Ash from two episodes, in 6x04 The Face Behind the Glass Ash tells about her young years.

Here Ash tells how she became Echo in 6x11 Ashes_to_Ashes  Ash/Echo says an important sentence (you will understand soon).  Ash/ Echo says "I've been wiped before" - to express that the life of 'real Ash' gets wiped and 'Echo' is born. This sentence opens a big door - does Ash/Echo tell us the truth?

Thanks for hints & answers Skai Engineer
