Who is the father of Katherine's child ?

I don't think its Klaus because she didn't meat him yet at that point. Her baby was taken away because she was a young mother and they did not wan't anyone to know about it. I think it is somone from the Gilbert family.

He surely can't be Klaus, vampire can't have children, they're dead...!! Nobody knows and it doesn't matter, Katherine probably has been making out with everyone since she was human, and at that time she could get pregnant... Von who? One of the many fallen for Kath =)

Katherine had her baby before she met Klaus and Elijah because she had her baby in Bulgaria. This is part of the main reason she was then sent to England, because she had an illegitimate daughter out of wedlock and had shamed her family so she was made to go to England. She had her baby in 1490. And she met Klaus and Elijah in England in 1492. So obviously they are two separate times. The father of Katherine's child hasn't been said, but until now all we are suppose to know is that its not relevant to the storyline. Maybe the writers will one Tag say who it is but at this moment it isn't important so its not being said. The father of her child could NOT be either Klaus oder Elijah since they were in England and she had her baby in Bulgaria. Its just an unknown person. It obviously isn't Damon oder Stefan either since they weren't in Bulgaria either and Katherine met them in Mystic Falls in 1864.

I really have no idea who it is, but im gonna take a guess and say maybe Klause??? I only say that cos she's been on the run for over 500 yrs oder more, plus she never got her baby back afther the birth of her baby girl... So thats my answer... But it could be anyone, if they ever tell us Mehr about it... So my answer as i sagte earlier is Klause...

khaul

It was never mentioned on the show.
Klaus and Elijah are Vampire and have been since like forever (Originals, duh!) and vamps can't procreate.

It's not klaus. that would be too predictable and he's a vamp. sooo probabably a Zufällig guy. who we havn't met yet. maybe he turned vamp after she had the child and we'll meet him. who knows?!

i think the father of Nadia is Stefan oder damon

i dont think the father is Klaus. it is possible. Vampire cant procreate but Werwölfe can. klaus is half vampire and half werewolf. he can have a kid. but i dont think the father is Klaus.

who is the father of katherine's baby

I would think for some reason its Alaric because when Katherine was pregnant Klaus and Elijgh were not in Bulgarian at the time neither was Stefan oder Damen and i think it might be Alaric because of the resemblance

Nadia Petrovas father cannot be klaus oder Elijah oder the Salvatore bros. because she has not met them yet. I just read her father was Marcos w
hich surprises me because the Zeigen never mentions the Father.

it's Stefan the father of Katherine's baby

Stefan Salvatore
