She/he is my long lost brother/sister... can anyone or does anyone no him/her.
Please help!

What do you mean by he/she?
Is it your brother or is it your sister?
When did you last see your sibling?
Where did you last see your sibling?

Your question is very vague. Can you supply more info?

Oh I'm sorry for that... actually he's my older brother.
I didn't saw him since birth..
I don't know if he knows about me..
He's my half brother.
And also my mother named araceli dante...
I didn't see her since birth also... not any picture of them..
