Brother would be 18 years old, and Fraternal twin to Siddalee Matfield. He would have the last name O'Connell.

A little bit of background.
Sidda's mother (Daphne O'Connell, NPC) ended up having Sid and her twin brother at the age of 18, their father (James Matfield) had been gone from the picture by then, and had no idea of their birth.

Because she was young, her parents arranged for the baby to live with their close relatives back in Ireland, but when she ended up having twins, she begged to keep at least one, while the other ( that would be you!) was sent to Ireland.

Daphne ended up dying in a car accident when Sidda was 10.
Their father is in Prison!
Their birthday would be in late January
They have just recently met, but just the once!

Sidda is blonde, blue eyed and freckled, she looks like their mother, but since they would be fraternal twins, he COULD look like their father, dark, tan.. green eyes.

I'll leave the rest up to you! IM Siddalee Matfield (Siddalee Resident) If interested. <3
