Arkilus Thunderbrew

Arkilus Thunderbrew is a dwarf said to be the father of Ragnar and Grimbooze Thunderbrew as well as the founder of the Thunderbrew Distillery in Kharanos in Dun Morogh.

Retconned?
It is possible that Arkilus Thunderbrew was retconned since in the Battle for Azeroth's Brewfest, Ragnar says that his father is Grimbooze Thunderbrew, who founded the Brewfest festival. Similarly, Pearl of Pandaria mentions that the Thunderbrew Distillery belonged to Grimbooze Thunderbrew when Chen Stormstout visited it.
