This is Billy's journal liesandtrouble. He co runs the tavern, and is a pirate gunner. I could see him knowing your gal, but not in the biblical sense, haha.
Grant Barber thebarber is a pirate and town barber surgeon, and overall grumpy old ass. He'd definitely know her. He used to frequent the brothel before Pike came around and he was friends with the old owner.
Vala fearlesswithout is sort of hard to explain. Haha. She lives outside of town with a pack of wild dogs, and trades in town.
Okomi, okomi once native medicine man, now runs a shop in town.
Jack Ferrington, jackfrosty is the one that would know your gal the best. The Ferringtons are INFAMOUS for frequenting the brothel, as did his father when he was alive (sometimes they'd go to the same lady without realizing it)
