Eh, in some bits during chapter 4 Simon and Ulrissa mention the fall of Givini when debating their moralities to each other, unless she's using it as a very elaborate cover for her true origins, I think it is safe to say that Ulrissa had some form of kinship for the Givini.

Of course that kinship could be for the Givini as an ethnicity, which could predate the Givini nation. But considering that Arclent had other Incubus Kings before the Incubus Emperor, and how disrupting those guys can be, I think it is somewhat likely that the Givini as we know them are unlike to predate any of the ancestral IKs, which I assume at least one of them was among the ones purged by the big abomination the Lustlord survived.

It is a lot of assumptions but I would put Ulrissa's age upper boundary as being after the previous abomination, not sure how that relates to the timeframe of Tanurak's existence and the dragons.
