But there always be possible that she is not a reincarnated as well.
As like she is a daughter's merchant that has the hightes authority and power.
Cause just like your good eyes, maybe her link of news have strong and efficient channels for she has the news of her neighborhood's country.
And i want to know, how she knew where letty's maid save her saving and how quickly she got those saving as well as the building contractor/creditor.

Plus it seems that the setting this world takes place in is further behind. I doubt Letizia's portrait would even be distributed in the neighboring country. She was described in the story about her being a goddess but it isn't like she has an extremely unique look to her either so it would've been hard to link the two together. It makes more sense for the heroine of the sequel to be reincarnated.
This new girl is definitely reincarnated. Letizia introduced herself as Letty but then later that girl called her Lady Letizia. I dont know if anyone else caught that.
