Lilia it is just a small Trader in San Pasquale, and the first Trader Scarlett will meet as she begins her quest. During daylight, she can be found outside in the center of the village. (At night, she seems to move into Mattheo's house.) She specializes in buying copper ore.
Speaking to her early in the game will give Scarlett some useful information about trading and prices. Scarlett and bring her any Copper Ore or other Loot she finds and sell it for ducats (which she can spend with Lilia or any other Traders she meets. She may also have an item of two for sale of interest to Scarlett early in the game, if Scarlett can scrounge up enough loose treasure.
