It may be helpful if you offer us a little bit more information about your Roegadyn lady, before asking around for family members. It would be useful to know some things like how old your character is, where they grew up and how they were supposedly separated from their family. Without a little bit of information it can be difficult for people to know if they have any characters who might fit.
I play several Roegadyn myself but it would be impossible for me to say if they had any connection to yours without knowing a little more about her.
