who is katherine's baby she gave a birth a girl ?

she had a baby girl
and her father gave the child in adoption

We don't know. They haven't said much. The baby might not even be mentioned again; highly unlikely but all they've told us is that Kat had a child and it was a girl.

The Baby would be LONGGG gone now. lol Remember she gave birth in 1490 XP well maybe the baby had a family that's family tree is still growing, but how anyone found them?
