Maybe a distant relative or something because of her hair.
Ok my prediction is that she is the illegitimate child of the blonde haired girls father (the asshole) because it’s saying that the goddess promised that the saintess would be born from that family every 3rd generation and her eyes are a dark pink and the blonde had red eyes (I see a tiny connection!!). Or another thought is that she is not related at all and the goddess was deciding to punish the blonde haired family for being power hungry/ ungrateful / sinners / horrible people (dare I say more).
So yeah that’s what I’m thinking and I really wonder if I’m right.
Yeah they look alike. Same eyes and same hair.
Here's my take on it:
The dead grand duchess was pregnant with a third child, which is why she said to the grand duke "If the child is a girl, I want to name her Esther". I'm guessing this unborn child is the MC, which is why she looks a lot like the grand duchess, but the grand duchess dies or gets killed while the MC is born alive but gets kidnapped or gets lost accidentally. This way, she grew up in the slums as an orphan despite actually being the youngest sole daughter of the Grand Duchy. This backstory perfectly matches with the prophecy "with the noblest status was born at the bottom of the empire". It's a huge stroke of luck that she ends up reuniting with her real family even if they all thought she was an adopted daughter, and I'm looking forward to them learning that she is indeed their biological daughter/sister.
Or, the wife of the dad is related to the family that raven is from. Maybe as cousin or something like that. Which can explain the grey-brown hair color and the pink eyes.
And the wife and MC have a lot in common in looks: looking identical in lots of ways (I would say copy paste, two peas in a pod.) so I do bet that MC is the biological child of the dad and his wife.
omg yes!!! and the mother might have been killed by her brother because they didn't want her to have a daughter because then that's more competition for blonde girl.
Apparently the duke wife is our FL aunt! Her twin sister is FL mother and the her adoptive father is her uncle; the big brothers are her cousins!
FL mother had a relationship with blond girl father and give birth to FL.
I don’t see this plot twist happening and it’s refreshing! to know!
I have been curious about the FL's whereabouts and background, and noticed that the Duchess ( The Duke's Wife who died?) and the FL have the same physical features.
From the brownish-grayish hair to the pink eyes, i think they are somehow related to each other. If they do, spoil it for me please!!!
