I think it should be Genevive, seeing as she is the eldest.
And here are the updated bios!
Emmeline -- Born January 29th, 1805. She's known as the more social princess and enjoys being out and about exploring and having fun. She's extremely friendly and very compassionate, but sometimes she's a little naive. She's very close to her family in the way that she has a special bond with each sibling. She has the power to control how the people around her are feeling, as well as make them see what she wants, all using only her mind. She discovered it at age 4, when she tried to comfort Henry after having a bad dream, and found out that not only she could contort emotions, but also that she could influence what people saw and thought. She is 5'7 with curly blonde hair and big blue eyes. Around family and friends, she goes by Emmy.
Henry -- Born January 29th, 1805. Henry is 17 minutes older than Emmy. Like his twin, Henry is fairly social and happy. He tends to never be too far from his sister, which is how it's always been. He has the power to speak to people with his mind. He can do it at anytime after he's made contact with them at least once. He unlocked it at the age of 6, when one of the stable boys brought his son. Henry became friends with the boy, and they were playing hide and seek in the garden. He'd already touched the boy once, and found that he could speak to the boy without the boy's consent, making it easy to find where his friend was hiding. Henry is 5'7, and has dirty blonde hair. Like his sister, he has blue eyes.
I actually got SO excited when I found the guy I wanted to play Henry, because he has the SAME EXACT birthday as the girl playing Emmy, and they are also the SAME EXACT HEIGHT, and I was just like "MEANT TO BEEEEE" lol
