You have not had custody in 11 years?
How old is your daughter?
You really need to put your own desires aside and consider what is best for her.
Yanking her away from your/her family just because you can seems fairly selfish on your part - and she's not going to thank you for it.
You and she might be parent and daughter but you are strangers to one another.
Your daughter doesn't know you and she's mourning the loss of the person who's raised her (your mom) and has been her world her whole life.
She'll be a teen soon - and that's not easy even if you've been part of their life from birth.
In your place I would not seek custody at this time.
I would move to be where she is, and get some regular visitation established.
If she's 11 or a bit older she's going to be an adult in roughly 7 years - your parenting time is pretty limited.
