what do i say to my neice i've never seen?

my neice whose 8 years older than me is on facebook and she's got her grandma (my dads ex/ brothers and sister's mum) as a friend, so i can easily get to her page. But because she's got her as a friend and she's recently found her dad, i think that she would want to get to know other members of her family. I have the same name as her dad and strangly his mum has the same surname aswell even though she's divorced away from the family. So if i said i'm her auntie, she would believe me, but what do i say to her?

ps. she's at uni doing accountancy and is in engaged.

[ummmm]

So she doesn't know you exist?

she knows that her dad has a brother and two sisters but she doesn't know us personally.
