You’ve kindly introduced a couple of Hethcanters via your Twitter replies. These are Lady Brunzarra Hethcanter, the second person to hold the office of Lady of Graces, and Ildra Hethcanter, matriarch of the Hethcanter farm in Immersea. 2/2
There's also Hethcanter, first to write of the Scalamagdrion, whom you introduced in Pages from the Mages III in Dragon #92.

Was Brunzarra the holder of a unique title that died with her? Were the Hethcanters ennobled? Is she or Ildra related the mage Hethcanter?

Thanks!

Did he get the share in the late 15th century? Yes. He made a pile adventuring, didn't know where to park it, and hit upon the idea of buying out the aging, ailing smallest partner (Shaluta Drennan, a retired widow of a ship captain from Marsember) among the inn's owners.#Realmslore
