@epheria we don't know quite yet because we're still unaware about the duke's dead wife's background. Also, the FL said they she and her mother were hidden from others so we can't really rule out the possibility of "the duke's dead wife was an abandoned princess and they married and she got pregnant with the third child (the fl) when the wife was in a carriage accident. The emperor rescued them, but the wife lost her memories and the emperor (with either good not bad intentions) hid the wife and her child from others." And MAYBE the dead wife's "body" that was discovered wasn't actually the wife but the body of someone who either resembles her or someone used magic to make it look like her.

AND I think that way because the duke's presumably "dead" wife's child was nowhere to be found. So I assume the mother is actually the duke's wife who lost her memories and the FL is the duke's daughter
