Who's your flower girl?

Hi Ladies,

I was just wondering who your flower girl will be. This past weekend my 6 year old boy cousin was asking me who was going to be my ring bearer. Of course I want him to be, but I don't know who the flower girl will be. He's the youngest in my family and the next youngest is me! On my fiance's side, he doesn't really have young cousins, they're our age and up, but... his mother's cousin's daughter is 5 years old. I never met her, or her mother and have no idea who they are. I feel like disconnected and weird to have someone be a flower girl who I don't know. When I asked my fiance (who's met the girl like twice) what he thinks, he's fine with it. But he has no relationship whatsoever with the girl, where we have a great relationship with my cousin! Does anyone have any comments to this situation. I mean it's not horrible having her as a flower girl, but I don't even know her and dont' even know if I will meet her before the wedding. What do you think?

Thanks!
Samantha
