Yes, its their daughter!

But anyways the epilogue, I dint know would be there, but then I'd read that major spoiler *epilogue part* two days back..... *long story....*
but yes it was surprising to see it, and to think of it now I'd never have thought Harry'd have three kids......

But I loved it when Harry said to lil Albus Severus, about Snape being one of the bravest teachers at Hogwarts.Yes thats got to be the best line for me in the epilogue, or possibly in whole of the DH.
