Do Venture-Captain Sayrin Fyrewine or the Gristmill lodge appear in any published Pathfinder adventures?

I’m looking for information about VC Sayrin Fyrewine and her Pathfinder Lodge in Gristmill. I can find cursory mentions of them on the Pathfinder Wiki here and here. Those descriptions seem to be taken from Seekers of Secrets and Guide to the River Kingdoms, but I was hoping for a little more detail. Do they appear in any PFS scenarios or other published adventures?
